Question Bout Parking Lights....

As I was just installing my new parking light clear corner's on my truck, and my newly painted 'gloss black' bowtie.......I noticed that 2 of the six bulbs #(3 on each side) did not work.........I believe the 3 bulbs are A. daytime driving light B. turn signal light C. and the other.......duh? Anyways, what is the 'other bulb'?.....it is the bulb closest to the side of the truck......The bulb is in good condition. And how do I make it work........I thought it was the hazard lights, but it is not.................?????? Thanxs

FMVSS standards require cars sold in the US to have visible lights from either side of the car or "side markers" that is the reason taillights are on the corner of the vehicle and if they´re not (like in imports) they have to put this little side marker light on the bumpers to be able to sell them in the US. They can function as turn signals but they don´t have to.

Then why does it not work........the bulb is good.....any suggestions?

Try swaping the bulb with one you absolutely know works (one that actually turns on for a fact, like the one from the other side) many times the bulb just "looks" good but it´s actually bad (terminals, not filament) does the other side bulb work? do your turn signal also work, do a logical step by step problem elimination.

mine work.... they come on with the turn signal and flash alternatly with the turn signal.
