Don Jr. - I second the motion on brighter lights. I had '50 Pontiac blue-dots on the back of my coupe. In bright sunlight they were invisible. I tried spraying the insides with glass frosting to diffuse the light - didn't help. I tried a bunch of different bulbs including LEDs - still didn't help. Finally I bought new '50 Pontiac style lights with 41 LEDs in each one. No more blue-dots, but at least I have brake and turn lights that can be seen.

Stovens - My '02 Harley Deuce and my wife's '05 Sportster use the rear turn signals as additional brake lights, so when ya step on the brakes they light up. Makes the bikes a lot more visible when stopping.
