I'm running a 12v system, no turn signals. I changed out the 1157 incandescents for LEDs (~$15) and LOVE them. I never thought about my visibility much until I entered a parking lot and a guy stopped and said, "Nice truck, but I couldn't see you from behind until I was practically on top of you." If someone who actually likes old trucks couldn't see me, then what about someone driving a POS while text-messaging?
I bought some off-the-shelf pair of red LEDs at AutoZone. Installation was nothing more than what you'd do if you changed out incandescents. The LEDs are much brighter, and don't look appreciably different. For concourse restorations, I understand why someone would keep the incandescents. For drivers, I can't understand NOT using LEDs. They are that good.
(To see what mine look like as driving lights and as brake lights, click on the YouTube video link below. There is a 2 second clip in the video that shows the LED tail lights.)
