1 piece fog lights

there’s a little pruple bulb in my foglights, it only works on one side, and i was wondering if the purple bulb is suppose to be there. and if there a way to get a replacement? or a way to disable it? the plastic gets really hot on the side where the purple light it on, anyone know about this? thanks.

purple light? thats definitely not stock. Where exactly is it? it could be one of those “city lights” or a strobe light. Typically they are skinny bulbs with a colored cover. You put them in the light by drilling a small hole in the housing of the light and then sticking the bulb into the hole.
