Glowteck H4/9003 LED Headlight Bulbs Conversion Kit - High/Low Beam 20,000 Lumen/Pair 6500K Cool White IP65 water-resistant Halogen Replacement Headlight bulbs For Bright & Greater Visibility

I did quite a bit of research before buying some LED headlights, analyzing cost vs brightness vs reviews and decided to get these. I was not disappointed! I put them in my car and WOW!!! They are easy to install and the brightness is as advertised! These LED headlights are simply amazing!!!

So far I love these bulbs. Extremely bright and relatively easy to install. Hard to accurately make a review of the longevity because I just installed them.

Don’t know about duration of product!

Pretty much plug and play. The cords to the light and the transformer could be a few inches longer so they actually reach a spot to attach it to metal. The transformers get pretty warm and can melt plastic so attaching to metal is kind of a safety thing in my opinion.

I was able to purchase from another brand the high and low Beam bulbs for lower price than the low beams were with this company. Had to return

I have had these lights installed on my 2003 Jeep Cherokee for over a year and they work GREAT. I switched from HID Zenon bulbs because I was tired of replacing the ballasts. I have separate bulbs for low & hi beams and I run Glowtech bulbs in both. Its like having the sun in front of you at night compared to regular bulbs. The adjustable 360degrees feature allows you to aim the beam exactly where you need them.... on the road. Also, I have never once been flashed by on- coming drivers because of light glare. I would recommend these bulbs.UPDATE TO ORIGINAL REVIEW (POSTING TODAY 1/13/2022) Originally purchased June of 2020. After using these replacements for over 2 years; they are still going strong.... NO PROBLEMS... EVERYTHING IS SOOOOO MUCH BRIGHTER. I REALLY DO LIKE THIS PRODUCT. I DEFINITLY RECOMMEND.

I bought these for my truck, and I bought a set of Sealights 12,000 lm / pair for another vehicle.The sealights (again, rated at 12000 LM) are considerably brighter than these, which are supposed to be 20000 LM.In addition, when these lightbulbs are adjusted properly (the top of the low beam pattern dropping 2" below the center of the bulb height at 25 feet), the high beams point skywards and are completely unusable. Furthermore and most interestingly, the high beams are dimmer than the low beams! (and yes, they are installed correctly in my F-150).Bottomline, the way these bulbs pattern the high vs the low beams is wrong and I do not recommend that you purchase them, I am returning mine.

Bought these for my dad's truck and he said they work perfectly. Nice and bright with a super easy install. Shipping was very quick and they arrived several days before the estimated arrival date.
