Review on 🔦 SPL 105W Brightest 5x7/7x6 Projector Cree Led Headlights: H4 Plug, DRL Compatible for Jeep Wrangler, Cherokee, Ford Van - Black Pair by Scott Rao

All the bulbs are plastic which is what I thought before buying. The low and high beams seem quite bright. I haven't driven the car since I installed it in my '91 Jeep. There is only a sticker on the packaging that says "Made in China". There is no schematic in the nose at all. Everything you need is made in China. The turn signals and daytime running lights will not work if you only plug the 3-pin connector into the yj factory harness connector. I'm not sure if this requires connecting cables. Also the bulbs came with a red wire with a 1/4" spade plug, don't know what that is for. I checked with a voltmeter although I'm sure it's not needed for grounding or the light would go out not work, but there is no voltage to ground when the circuit is on.
