Re: [MBZ] Headlights Q; dual-filament H3?
I think people might be mixing up R2 (dual-filament) with H3 (single filament, usually a fog or driving lamp). The H4 was the first and remains the only dual-filament halogen (non sealed-beam) headlamp bulb, introduced in Europe in 1971. Before the H4, basically all dual-filament lamps used R2 (otherwise known as a bilux), a non-halogen dual-filament bulb introduced in the 1920s and used into the 1980s, well after the H4 was released. In fact, even the (Euro) W123 originally came with Bilux bulbs. H4 was an optional extra and/or included only on higher-spec six-cylinder models. Ditto for the W115, which had an H4 option on later models. The electrical connector for R2 and H4 is the same pin configuration, but the bulb base is different One thing is for sure: H3 bulbs are mono-filament and always have been, just like H1 and H2.

Re: [MBZ] Headlights Q; dual-filament H3?
I think people might be mixing up R2 (dual-filament) with H3 (single filament, usually a fog or driving lamp). The Frankenheap and my Unimog both have R2 lamps. As they burn out I've been desoldering the base flanges and modifying them to accept an H4 in the center. The assembly then fits into the R2's site, the filaments end up very close to the R2's plane, and the result works well and is brighter. (I believe the H4 was a derivative of the R2 and shared the same filament geometry.) See: http://userweb.windwireless.net/~jimc/frankenheap.html#h4 Ditto on the weird 10086 lamps used for the heap's fogs. I break off the glass and solder an H3 to the base. See: http://userweb.windwireless.net/~jimc/frankenheap.html#fog10086 Regarding the original question, I don't see why that because the lens of the lamp assembly has an H4 molded into it that one has to assume that this is the bulb specifier. Isn't the lamp lens customized for lighting patterns in different countries? Maybe 4 was the US pattern? -- Jim ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Headlights Q; dual-filament H3?
hi Jim! just in case you didn't already know, Daniel Stern (love him or hate him) offers H4 lamps in a variety of wattage combination on an R2 base,... for $11-14 for standard wattage, it might not be worth the trouble to bother with brewing your own.;-) http://danielsternlighting.com/ (i couldn't get your links below to work for me.) WRT the OP, he said that his lamps were labeled H3, not H4. H3 and H4 are both bulb type specifications, not related to point of use. for example, you can order H4 lamps for your car with lenses designed to be used while driving on either side of the road. cheers! e On 15/Dec/10 06:41, Jim Cathey wrote: I think people might be mixing up R2 (dual-filament) with H3 (single filament, usually a fog or driving lamp).

Re: [MBZ] Headlights Q; dual-filament H3?
Dieselhead, i haven't seen any response on this, but just to try to follow up; since i happened to be on the RealOEMsite (http://www.realoem.com/bmw/) i popped into the archive section and checked what was listed for the Euro /5s to try to verify that a dual-filament H3 was used. they show the headlight bulb on the /5 to be a dual-element 40/45W item (BMW P/N 07119978396) on every /5 model i checked, but it's not like anything we call an H3 (now). here's one link to an example of what that looks like: http://t2.gstatic.com/images?q=tbn:ANd9GcSApmDBRnXhSkjy5PPDVQhuuJKFNfk-UGyDNFn6ZtmJkLRwJwnv is that what you have on your /5, and what you're calling an H3? i can think of a couple of possibilities other than the fact that you might be mistaken; one is that RealOEMs listing is not accurate... another is that something different was used in the US. in any case, if you or anyone else can show any evidence that there was indeed a dual-filament version of the H3 bulb, it would be greatly appreciated. cheers! e On 13/Dec/10 14:45, ernest breakfield wrote: Mr/Mrs/Ms Dieselhead, i have seen several applications of H3s where they were used in separate High and Low lamps (my 1150 Oilhead is one example), but if you can just how me a link to any spec anywhere that states that H3 bulbs have more than one filament, i'll believe you. so far, i've never seen any reference to any H3 bulb that had more than one filament, especially since they have a completely different base than H4s and only single-wire leads instead of connectors.

Re: [MBZ] Headlights Q
I think these have insert bulbs and are not sealed beams. I also assume they are not original as they have Volvo imprinted in the glass. The problem I have is that there is a huge difference between high and low beam. I find the low beam does not provide sufficient view ahead and unfortunately most of the time it is not possible to use high beam due to other traffic. So, I am looking to improve without breking the bank. I think I will order a set of the Bosch and see if it makes much difference.

He did say he has high/low beams but the lows are really bad. I wonder if someone stuck in the high-beam lamps from a Volvo and used a dual-filament bulb.

Re: [MBZ] Headlights Q
I can look again but I believe it says H3 on the lens. I thought that normally, 2 lamp systems had larger diameter than 4 lamp systems back in the day when we all used sealed beam lamps. Am I wrong? In any event, these definitely have both high and low beam. The 115 has only 2 lamps obviously apart from the fog lights. They work ok too as additional close light but not too good for travel at highway speeds - if I remember right, they also go out when one switches to low beam. I do not do a lot of night driving any more but find that I need much more light than I once did. I drove the MB back from the lake 2 summers ago in the dark and it was an awful trip. I felt like I was driving through a tunnel for a good part of it. Part is 2 lane and much of the 4 lane part is close enough to the other side that one cannot run on high beam most of the time. Add to that the concern about wildlife on the road and it is not a pleasant trip. So, I am looking for better light in case I have to do it again. I had a set of the Bosch in a Chevy back in about 1975 and remember them as being good. I also had a single one in my 1979 Goldwing. I think I still have it but only one so I don't think I want to do this until I have two and it won't get actually installed until April likely as it is cold here and the car is in the garage for the duration. I put the battery tender on it yesterday and that is about all I will likely do with it until the weather warms up a lot unless I decide to haul seats inside and work on them in the basement.

H3 lamps are single-filament bulbs; what should be in there should be dual-filament lamps (like H4s) so you have High and Low beam from the same lamps. obviously some PO was screwing with your cars lamps; have you stood in front of them with the lights on in both High and Low to see what's actually lighting up? i've seen some examples where people have played games with putting Highs only in where the Fogs go, etc, but odds are better some DSPO took H3 lamps and tried to use them with H4 bulbs (which won't work well, as you're finding out)... no telling exactly how they'd do this since H3s have a single Pos wire lead and ground through the base as opposed to a 3-prong plug like H4s have, but it'll probably be pretty clear what's going on as soon as you pull the lamp housing out to see what's behind it. hopefully they didn't bugger up the wiring trying to use the wrong lamps! in any case, i'd recommend Cibié H4 lamps over anything else i've tried; we've got some in the family that are still performing well after a decade or more in use. Hella lamps always seemed like the difference between High and Low was too great and the lenses seemed like they cracked very quickly in all the cars our family has used them in (giving us the 'opportunity' to try something else). Sunpowers were terribly poor at directing light and harsh on glare for oncoming traffic. the rectangular IPFs i've tried also had this problem, as well as some others. if you're getting light out of the main lamps on both High and Low settings and it really is an H3 housing, chances are you have an H4 bulb in an H3 housing and need to get a proper H4 lamp housing to use with your H4 bulbs. get good ones, and you'll probably never need to replace them, and wonder why you've been living with such poor lighting for so long. ;-) cheers! e On 13/Dec/10 09:07, R A Bennell wrote: Some may recall my questions about upgrading headlights on my 75 300D.

My first memory is the headlamps on 1985 1/2 Ford Escorts, but there might have been an LTD or Thunderbird or something with fixed headlamps before then. Or I might be wrong in remembering Ford as the innovator that got the law changed. MBZ had replaceable bulbs for 1987 model year.

Re: [MBZ] Headlights Q
Mr/Mrs/Ms Dieselhead, i have seen several applications of H3s where they were used in separate High and Low lamps (my 1150 Oilhead is one example), but if you can just how me a link to any spec anywhere that states that H3 bulbs have more than one filament, i'll believe you. so far, i've never seen any reference to any H3 bulb that had more than one filament, especially since they have a completely different base than H4s and only single-wire leads instead of connectors. (i checked again briefly just for giggles, but didn't find anything like a dual-filament H3 listed anywhere, including Osram/Sylvania and Hellas websites.) doesn't mean it didn't happen, but i've yet to see it and would appreciate it if you can help show me an example. cheers! e On 13/Dec/10 13:58, Dieselhead wrote: Not so.
