I have the tulsa fog lights. My bulbs burned out at 1500 miles. Replace both bulbs because When my bulb went out... before I even got home the other bulb went out too. Might as well replace both while you have it apart. The bulbs you need is a very common H3 bulb that you can get at any Pep Boys or auto store. The lense of the fog light is yellowish.... the bulb is clear.
