WFLNHB 4 Pcs 9005+9006 Combo LED High/Low Beam Headlight Conversion Kit Light Bulbs 6000K White COB Chips HB3 HB4 Replacement for GMC Sierra 2500 3500

Lights work good they are bright but don’t have the coverage I wanted only can see 1 car length in front of me

these work, but let me explain why the reviews are inconsistent.with the halogen lamps I removed they were all clocked so the plug points down & they locked securely with protective dust cap. they lock in & out very easily. low beams are dipped to prevent light from going straight ahead, they emit in a circle so they reflect well as long as you lock them in properly. highbeams are all clear glass, also emitting in a circle.These leds differ in that the high & low beam bulbs are exactly the same as each other, and they are 2 sided. light comes out of the chips however they point and not circular.this is the problem, because when installing, the locking mechanism isnt clocked consistantly, and it feels flimsy too. so you cant get the emitters completely level, and so they reflect randomly even if you try to line them up. also they are polarity sensitive, so you plug them in and they do nothing, but then you flip the plug and they shine.and of course engine bays are packed, so I had to pull out my battery and air filter to get at the lights, which makes it a pain to check polarity as well. the dust caps cant go back on cause of the cooling system.so while you can't beat the price and they do produce a lot of light, its a lot of trouble, and they might not work well. it seems like these same issues will apply to most led headlights on the market, and explains why people still use expensive halogen bulbs

Buying high and low beams in these was stupid, the high beams give you less light than just using your regular headlights. All you need is a regular set with out high beams. You will never use the high beams when your driving I promise. And they honestly don’t fit as good as the regular sets when taking them in and out you can tell it’s not very snug…

Ok illumination. bulb case broke on instalation had to super glue it. Ok for the prize

excellent product good price very bright.

I would like to make a comment for buyers (recommend 5 STARS btw) to be aware of. I received my 1st set very quickly. Upon installation I discovered that 2 of the bulbs would not turn on. They were replaced in 2 days by the seller (another 5 stars!!) upon getting the second set today, 3 of them would not turn on. I figured "user error" and started inspecting everything. The conclusion is that the plug in doesn't have the factory "Alignment groove" or "one way limit". After this I flipped the connections 180 degrees on the non working lights. All lights now work and I wish I had known this sooner before returning the 1st set. I was very happy with the response time for both sets and am very happy with this cost effective upgrade for my Yukon, I may get some for my Sierra and Denali as well. Perhaps the Manufacturer can fix this or instruct customer with a pamphlet in the future? That's my only suggestion.2000 Sierra 325k2001 Denali 212k2002 Yukon 180kThey still run!!!

The right (passenger) low beam went bad 2 days after installation, otherwise, I like them, 2nd set on the way, I know they allow return, but I may keep the extras for the price

What I didn't like about my package was one of the lights didn't work it was blowed and the lights didn't fit in the lightbulb housing the part of the Lights that goes in the housing was to big to fit in the hole
