Incredible brightness upgrade!

Just installed these on my car and the difference is unbelievable. The 6000K white light is so crisp and clean - night driving feels completely safe now. Easy plug-and-play installation.

Great for country roads

I live in rural Montana where deer are a real hazard. These lights give me that extra reaction time. Can see at least 50% further than stock halogens.

Great bright light

Amazing lights! Beam is bright and wide. The price can’t be beat. Handles heat great, the separate block handles heat better than the all in one. I have ran multiple brands, my friends run the Ultra 3 and these blow them out of the water.

EVIL ENERGY AN Male Flare to NPT Pipe Fitting Adapter Aluminum Straight Black

Butch

Gas lines

Very happy with the look and the install. Takes a bit to figuring out the pieces you need. I wished they sold the stainless steel hose and black fitting in a kit. I hade to buy separately. Getting the parts to fit up wasn’t too bad. Figuring the right adapters was a bit tricky.
