Joey, thanks, you are totally right. What causes the dimming of lights (incandescent bulbs), or the non working of some of the LEDs is the drop in voltage (now that I think about it, makes perfect sense). My plan is to go completely with LEDs, for all turn signals, brake lights, etc. However, and in the meanwhile, would a capacitor solve the problem of the drop in the voltage? Believe or not, I hate the Big Bag Theory tv show ;)
Thanks a lot for the info. Javier. On Sun, Jul 4, 2010 at 11:23 PM, Joey Kelley <[email protected]> wrote: > Javier, > LEDs are extremely sensitive to voltage compared to normal > light bulbs.
