i had a set that came with my clear tail lights they were not bright at all.
i was worried that someone will rear end me . even the brake lights dim.
if you get led bulbs (BEWARE) they flash a lot faster and they might blow a
fuse.got them off ebay. their is a module that will solve this problem but i
never bought it so i don`t know if it really works. it`s on ebay.
