Have a question about our Fog light systems or troubleshooting a problem?

Check out this list of common questions to find the answer you are looking for!


What is the difference between MKI and MKII? . . .

The MKII Lights are our newest version. They offer improved brightness, better build quality, laser engraved bodies and a purer white light. We highly recommend the MKII option! Both the MKI and MKII units will fit the same applications.

Are these the bulbs only or are they entire housings? . . .

Our LED fog light kits are easy plug and play bulb replacements, no need to replace the entire housing etc.

Are the resistors/ballast/etc built in or are there seconary units? . . .

All of the companents are built into the bulb, there is no need for secondary units etc.

I think my fog lights may have blown a fuse. . . .

ALmost all of our F150 have no trouble running these fog units, but occasionaly we have had reports of a blown fuse. This can be casued by a variance of things, sometimes not directly related to our bulbs although the bulb(s) can be shot if the fuse breaks. If you experince this issue and are confident the fog lights are at fault, you may need to install an inline resitor to help limit the peak of electrical charge running across teh fuse.

Are these legal for road use? . . .

Our lights are approved for use both off-road and on-road use!

Which lights match the 2015+ OEM LEDs best? . . .

The MKII fog light option with out a doubt is the best match.

Which lights match the 2009-14 OEM HIDs best? . . .

The MKII fog light option with out a doubt is the best match.

On my 2004-08 the high beam light dimly shows with my MKII fog lights. . . .

This is normal and no casue for alarm. The light should not be affeceted in funciton and is much brighter when actually activated by high beams. This is casued by the grounding function of the fog light assembly being tied to the high beam system.

On my 2004-08 the high beam activates when I activate fog lights. . . .

This is a rare scenario but we have seen it. This is caused by the grounding function of the fog light assembly being tied to the high beam system. You will need to install an inline resisitor with your fog lights to reduce the electric load. If that does not work then try grounding the ground wire itself to the frame of the truck.
