Great tip on the Brite Bulbs! Combine that with a sequential turn signal mechanism and you'd have something there that stands out for safety! Something that makes you long for turning, even if just driving in circles around the block at 5mph

Only about a $300 upgrade, all-in-all...
From what I gather from my off-road friends and their trucks, avoid LED conversions completely. Old vehicles don't have the reflectors new cars have in their houings, which are crucial for an wide, bright light patern. Led bulbs in old-skool housings give a dimmer and beamy light that is only visible head on, and poorly seen from even slight angles in retrofits.
