"Carefully read the technical data on underground lightings website. New technology has illuminated issues that have caused issues in the past. The LED bulbs for my 03 Silverado were an exact easy install.Significant improvement with no issues. "

"I bought some LED headlight bulbs for my Chevy Trailblazer. They are so much brighter than the ones the factory gave me. For someone with issues seeing at night these have been incredibly helpful. I'd definitely recommend. "

"I bought a couple from another place that said no hyper blinking,, well that was true for the 1st 2 minutes .. These lights i bought from these guy did what they said.. And bright omg.. they are bright.. Got my business from now on"

"Bulbs arrived and one was faulty. They expect me to pay international postage to send it back and then pay the international postage for them to send out a replacement. Utter Joke! Will never use this company again."

"I purchased a HID and LED set from Underground Lighting and was having some issues with the install (OE!!) To his credit Danny A. was patient and helpful which led to a positive conclusion and now my 2002 GMC Yukon Denali XL has some great lights.

"I got this kit after talking on the phone with the owner. We talked about another kit and the things he said about the other kit by another seller were on par with things I had researched. The kit was a direct plug-in, easy to install. I have aftermarket lenses that came with a punch out for the seal which made things a little easier for me but would be easy for someone to use a small hole saw in the factory dust covers.

Pictures show the stock brightness then what it looks like with the kit. There is a shadow in the picture that I had to fix by drilling a couple of spots in the headlight housing. That is not a fault of the bulb and had everything to do with the aftermarket housing that I have."

"Pretty impressed, even for the price. I hope they last because they are a huge improvement and had a good cutoff which made them easy to adjust. Got the 60w low beams for a coworker of mine we call “coach” who was having trouble seeing on the dark country roads. He’s pretty happy which makes me glad I did the research and found quality parts rather than being lazy/cheap and picking him up some chinese junk on Amazon. Might have to get some for my truck."

"I just purchased a pair of fog lights for my Lincoln Navigator as the stock bulbs were just not bright enough. Needless to say the difference is simply amazing. Great job Underground Lighting!! They are much brighter than the fog lights. I accidentally ordered the first time. The fog lights are en route back to you guys. Thanks for all the help and great customer service on returning them due to my lack of paying attention. The light setup is awesome. I would recommend these to anyone who is looking to upgrade there vehicle's lighting."

"Been running these on my mini cooper for over 6 months. Never had an issue, love the look! I've been recommending this place to all the people who come into my junk yard hoping to find the pricey bulbs. Love this place, cant wait to upgrade all my bulbs! I love the lights once I put them on and their customer service was very helpful I told them what I was looking for. Then this suggestion what I should get, and they nailed it."

"I upgraded from stock lighting to the HIDs and am blown away. I can see more and see it clearly. The install was painless and easy, and while I did have a couple of questions, my emails were answered within minutes, on a Sunday! I’ll definitely be upgrading the rest of my lighting as well as my wife’s car. Can’t beat Underground Lighting.

"Used these for our 04 Malibu. The original halogen bulbs actually melted the turn signal lenses :( These fit great, are super bright, and do not cause rapid flashing! Very happy with this purchase, and thankful for the help about the physical size of the bulbs. Great product and great customer service! Much appreciated!"

"The original set of 3157 switchbacks I purchased for my 2016 F250 had an issue with erratic flashing and flashing white every so often. Worked with Danny and he ended up sending me a different set that work as expected. Really love the all white light look on the 2016 F250 given that the turn signals are huge on this truck."

"I entered the information for my vehicle into your website and it told me which bulb to order. I receive the wrong bulb and your answer was immediately to tell me that I messed up and ordered the wrong item. I realized I did mess up by choosing the wrong company to do business with, so I stuck it up and pay for shipping to send your merchandise back. Then you want to further screw me over and steal $30 from me and act like it’s my fault again. And you wonder why Amazon is edging everyone out of business. You are the reason. You should have named your company Underhanded Lighting.

"Customer communication and delivery is good…but that’s where it ends…their website is misleading. You/I put your vehicle info and they list recommended LEDS…upon purchase the bulbs didn’t work as advertised, let alone at an expensive price! 'Their recommended' bulbs did not work as advertised…they said it doesn’t work with my truck application??…their website said these were the bulbs to purchase! Because it was 'installed', they refuse returns, though they also advertise 100% customer satisfaction, 30 day returns! They said, technically the bulbs are not a manufacturers' defect...plus after 2 days, they melted completely! Again, they said it's not a factory defect, they melted because your vehicle application does not work with these LEDS...BUT YOUR SITE RECOMMENDED THEM!!! Now I’m out $70!

"I was a little hesitant at first about the cost of upgrading my lights but wow I am so glad I did. Ordered a set of led plug and play bulbs from Danny and I must say they look fabulous, Danny was on the ball with customer service and very quick and efficient, needed a decoder set for the fog LED fog lights but once Danny sent me those, they work amazing and are very bright! Highly recommended! Easy to install plug and play. Very bright and great quality fit. Please check the website if you are looking for any kind of car lighting accessories. "
