Vehicle's information: 2016 Honda Fit EX-L

2016 Honda Fit Fog, Reverse, and Headlights

Great pre and post sales support. Installation was a bit tricky for me. But after reviewing some online content it went in pretty good.

Vehicle's information: 2018 ford f250

Reverse lights

Easy installation. A lot brighter than stock lights.

Vehicle's information: 2017 Ford F-250 Super Duty Super Crew

Super Bright Reverse Lamps

The older I get, and the more tinted my truck windows become, the greater the need for additional reverse light. The lamps really do the job with much more white light that the factory lamps.

Worth the buy!

Extremely bright! Easy to install. Worth every penny.

Bright and worth it.

Very bright! As you can see from the picture posted. The bottom is my stock bulbs and the top is these bulbs. Literally looks like headlights.

What are CAN Bus LED Bulbs?

when we say CAN Bus LED bulbs, they are the easy plug-and- play LED lights bulbs which are made specifically for the vehicles built-in CAN-Bus system. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly.

To see if your vehicle operates with a CAN Bus system, simply remove the bulb you're looking to replace, start your vehicle, and if you have a "Bulb Out" message on your dash you have a CAN Bus system.

Best lights ever

Ever since I’ve replaced my lights, my car is now more visible and better to be seen by other drivers. Must by if you have lights that are very low and hard to see from a far away for other drivers. Can keep you safe and the other driver safe.
