QuoteSo, with a 10 volt supply, I will be looking at running parallel strings of 4 series LEDs, and hopefully the regulator will be quick enough for the flashing function of the Brake Mod.
Quote from: RCE on December 29, 2009, 11:16:04 AMCouple of points, using LEDs inside the standard tail lamp unit will invalidate the E mark.... issue then is if you get rear ended they have a get out of jail free card if the vehicle inspector finds them.Unit failure, think about splitting both circuits so that if one section fails you still have some rear light.I have gone the supplemental LED route (based on the bullet), and reckon they look and work well. Unfortunately since building them the snow and ice has meant I haven't tried them on the road. Intention is to get some video shot of them to see how effective they are. For the time being here is some video of them shot outside my garage http://www.youtube.com/watch?v=AkGS2Iff4g0

Quote from: martin999 on December 31, 2009, 11:14:11 AMThanks for the input RCE. I take your point about the e mark on the rear light, but TBH there are a few insurance 'get outs' on many bikes that have been modified. I'm no expert, but following your train of thought does it mean that the extra brake lights you have (which look really good BTW!) are illegal as they are not e marked?Some built in redundancy may be worth doing and I'll consider it as the build progresses. Keeping in mind though that it is replacing a single dual filament bulb. The LEDs should be much more reliable anyway and I always check the operation of all the lights before I ride. I would have thought the chances of bulb failure whilst riding would be higher than failure of the LEDs.
