Review: Dont question it, buy it! - 81 c10 4 headlight set up, fit like a glove, super impressed with quality. Even back of headlamps have a paint coating to protect them from elements. Also the "stands or perches" on back of lights that go into the grooves are metal with quality welds. They look completely original but brighter. Worth every penny.

## Questions & Answers

**Q: I just purchased these to replace my originals. I would like to know where does the city lights connect to?**
A: Connect them to your park lights or wire them up to a rocker/ toggle switch.

**Q: I started to install today but realized the old bulbs have 2 prongs and these have three.  Any advice?**
A: The 2 prong bulbs are for high beam. You can use the 3 prong no problem, you just won't have the operating low beam on that unless you wire it to work with the other low beam. 

I used to run the 3-prong bulbs in all positions, so that when a low beam blew out, I could just swap it over to the high position and keep going without trying to find a new bulb right away.

**Q: The city light wires, what type of bulb is that ?**
A: The bulb is a H4 Halogen bulb . Each bulb has three tabs.

**Q: will these fit an 89 k1500? the quad headlight trucks? they are side by side**
A: 89 - 91 Chevy trucks with quad headlights use relatively unusual 150mm headlights. 4x6 headlights like these are equivalent to 165mm, so they are too large to fit these trucks.

### ⭐⭐⭐ Almost
*by A***I on September 14, 2025*

Glass lens. Metal back. Awesome. They don't fit well. Feels like smaller than the bucket. The front bezel kinda centers it. Also i didn't realize that h4 bulbs are different from the sealed beam. It would be nice to have convention harness in the box. Because they are wired wrong into a 86 chevy truck i can't tell if they throw a good pattern.
