[Life begins at 250k]
don't know if this is of help but I found the short front indicator lead from the bulb holder to the connector which is usually 2 black leads work the stock lights by completing a circuit whichever way round they are fitted. ( hence no hard and fast quality control )But when you bring LED into play the live wire from the connector usually orange one side and blue on the other MUST connect to the base of the bulb holder or the offending holder will cause the bulb to either not light or stay on constantly. Took me 3 days of headaches to sus out. I have full LED intergrated clear rear lense and clear front indicator lenses with orange led bulbs up front and led flasher unit to slow the flasher rate back to normal. they work and look great on my blackbird and make the back look much slimmer with the rear indicator stems removed and the 4 into 1 yoshi[/quote]
