KC 4" Rally Lights
I wanted something small, but with a lot of light. I've had KC lights before and was always impressed with the quality and design. These lights deliver what I was looking for.

Easy Install with KC Harness
These were a breeze to install on my 2023 Bronco Black Diamond with the prewired auxiliary switches and the KC HiLiTES wiring harness. The light they produce is good, but easily out outpowered by the factory Ford Bronco LED headlight high beams. Very happy!

Dismal quality control- fell apart in my hands.
First and last KC product for me. To change bulb, two screws are removed, and then glass lens and reflector come out as a unit. Not so. I removed the screws, and pulled on the glass lens with a fingernail. The lens came loose by itself, leaving the reflector and rubber gasket in place. The adhesive holding the lens to the reflector was useless, and I wound up scraping all of it from the reflector and glass, and starting over with my own adhesive. Then reassembling the lamp. Moreover, the positive connection inside the housing is not completely insulated, which could result in a short. Disappointing product.

Perfect and exactly what I needed.
Had a five position light bar on the roll bar of my Jeep CJ5 and had to remove it and reposition lights thanks to the install of a new soft top. Put two 6" KC's on the windshield and bought these for the front bumper lights. They are great and kept the "old school" look for the 1973 Jeep. They are plenty bright for use as work lights when using the winch but still can add 100 watt halogen bulbs to these if ever needed.

Good little lights
I wanted them more for aesthetics than use. They are reasonably bright on a dark trail. Yellow light that penetrates so so. Look great, easy to install.

Nice lights
Good fog lights, a good amount of light for their size. I didn’t want them up by the windshield and did not like the look of them on the overrider bar so I drilled a couple of holes in the bumper and waalaa. I like them there and they light up the road and trail well.

KC lights
Easy install. Wire harness not to good. Wires to short to run on front bumper. Had to modify for it to work. Lights are decent brightness. Not over powering. I'd say a good bag for the buck. I'd recommend them for the weekend warrior not so much for the extremist.

KC rally 400 Halogen lights
Seems to be heavy duty. Install was pretty straightforward. KC covers diffuse brightness but add plenty for street use. Substantial for off road use with covers off.

Just 4 inch ligts
They were easy to mount on my new roof rack. I only mounted 2 in the fron, I did not want to interfere with the kayak, but they're small enough I coulda put the 2 inside lights without a problem. Mounting them is one thing, wiring is another. I paid a place too mush to wire them for me. Thing is, probably because there's only 2 and they're only 4 inch...they aren't all that bright.

Very Nice
I bought these without the wire kit as my truck has the wire harness from previous older KC Lites. These new lites are great, very good quality, perfect size for behind my grill, and they really light up the road nicely. I never had lights with the spread beam, they work great, all my lights in the past were either wide beam or spot beam, spread beam on these lites gives you the best of both.

All around great
Got the lights after I measured wrong the first time and gotta admit I'm glad I did. My truck is a daily driver and a weekend worrior type deal. The lights are great when driving at night for extra vision, and they're also grreast for off road seeing everything. Definitely worth the extra money you might spend.

Great lighting
Metal housing spread beam is good for lighting up sides of the road. When bulb burns out will upgrade it to an LED bulb but overall satisfied with the product and looks good too
