Hi have 100 watt halogen bulbs in mine as did Matthew before me (upgraded wiring) which strictly speaking are illegal but never been noticed by any MOT tester.Bob Craig Q2-063Sent from my Galaxy -------- Original message --------From: "list...@liberator-systems.co.uk" <lists...@liberator-systems.co.uk> Date: 23/07/2023 13:45 (GMT+00:00) To: Quantum Owners Group <quantumowners@googlegroups.com> Subject: Re: [Quantum Owners] Headlamp upgrades The headlight rule change re LED etc. in 2021 was pretty silly IMO and came in for much criticism. Why pick April 1986 as date ? Surely it would be better if all older cars were allowed to improve their halogen style headlights. My saloon is 1985 reg so luckily I can legally fit led bulbs. With regard MOT test I suspect failure is going to be down to how stringent the individual tester is. Decent brand led replacement bulbs should give correct beam pattern - after all the manufacturer must have spent considerable time and effort developing and testing. So if beam pattern is correct why fail? One option of course is to just pop in some old H4 bulbs just for the MOT.John On Saturday, 22 July 2023 at 20:36:04 UTC+1 Mick L wrote:
As far as I'm aware they allow hid etc if they have washers and self levelling? Correct my if I am wrong?

I have created a mount with the new 90mm Hella unit and a small indicator( also modular Hella but about 40mm dia) . The 90mm unit is a bi-xenon , it has a single bulb with a flap to create the dip cutoff pattern needed for mot. Two additional items are also needed for xenon ( not sure about led), that is headlamp washers and self levelling. Hella sell universal kits to go with the 90mm products , but the washers are easily and more cheaply done with a universal windscreen wash kit. Levelling is a little more tricky, the Hella kit uses ultrasonics , I am using OEM lever arm sensors(BMW mini). I am making up a small driver module that will read the inputs and adjust the std OEM headlight motors . I will publish the build details including firmware as open source as I do all my work on GitHub. My friendly MOT man is going to let me use the beam aligner out of hours to set it up and confirm all is well before the actual MOT test. But I need to finish getting the car back on road before I can do that.

There’s a lot of conflicting guidance online, which seems to stem from some changes to the MOT rules. So I started there, with the relevant part seeming to be section 4.1.4: https://www.gov.uk/guidance/mot-inspection-manual-for-private-passenger-and-light-commercial-vehicles/ If I’ve understood it correctly, replacing your halogen bulbs with HID or LED equivalents is forbidden for any car used after 1st April 1986, and will lead to an automatic failure (‘light source and lamp not compatible’). But the part that’s of interest to me, the amended rule, seems to state that there is NOT an automatic failure if you have replaced the *entire* headlamp unit with an LED or HID alternative. I’m presuming that they would need to be CE/UK CA marked, or given an E number but, again, that aspect seems to generate conflicting answers – and imported Japan-only or USA-only models seem to be able to pass MOTs just fine without those markings from what I’ve read. There seem to be loads of possible replacement headlight units out there so I was wondering firstly if I’ve understood all of this correctly (anyone know a tame MOT tester?) and secondly if any of you have replaced your Q’s entire original halogen units with an LED or HID alternative. I’d be fascinated to hear what you picked and how it played out. Hope you’re all having a great weekend.
