Can I mount my lamps upside down?
PIAA lamps are designed to function properly mounted upright or upside down, as long as a few details are taken into consideration. When mounting your PIAA lamps opposite of their intended installation, remember that lamps with a "Snorkel" type wiring grommet in the back of the housing must have the opening facing down. Also, the PIAA name must read right side up so the vent on the bottom can drain. 9O Pro lamps have a vent on the back of the housing in the center. The opening must be facing down. Proper auxiliary lamp aiming is the most important part of an installation. Refer to the Light Aiming Instructions on this web site for proper alignment.

What is the difference between a fog light & a driving light?

This is the third bulb to blow out in four months; why does this keep happening?
Bulb failures caused by voltage surges have become more common as new vehicles have placed greater demands on factory electrical systems.
