I had to change a burned out Brake light bulb so i thought i would try LEDs. Sylvanias were a direct fit, and the package said (in small print) for off road use only.... they don't seem any brighter (its a sunny afternoon) so i guess i will try them out for a while then get back. Oh, while checking out the tail lights I discovered that the bottom set of lights come on when the FOG setting is on....nice to know....I still haven't bled the brakes... seems all i have read and seen on Youtube, indicates vacuum method at the wheels is fine,,, as long as you DO NOT get air in the ABS pump....
