Always the best quality...never disappointed

Very bright lights. Wondering what the resistive value is vs stock bulbs. For flasher applications, flashing frequency dramatically increases due to low resistance. Wish they offered resistance matched bulbs. First video is stock then with carbide 2 bulbs

I installed a set of the GTR 2 LED bulbs in my 2004 Corvette. Very happy with the increase in light. These cars were notorious for not having good light. Now I can actually see. Very happy with the amount of light they're putting out and with the customer service I received. Please see the before and after light pictures.

I have change all Internal and external lightings of my Honda Civic with the help of many staffs at GTR Lighting. The staffs have helped me in many ways and I would like to thank and appreciate the efforts of the following staffs: Anthony C, Jamielle, jimmy, Austin W, Garrett CSR, Elliot AC, AaronH, MJ. And without a doubt their lighting products are excellent.

the lighting is great

These are the brightest bulbs on the market. This is the 3 rd set I have purchased. Great bulbs.

Great light and bulbs. You can hear the fans running when car is on place. Big NO. Thank you!

I have had the lights for a few weeks. They are 100% better than the stock halogen bulbs. The lights look to be well made and easy to install.

Superior construction on the bulbs themselves, but world-class customer service!

Very happy with my lights! My son got them first, for his car, told me about them, and then I ordered them! So happy I did! Amazing difference!

After failing results with products from a few other manufactures I ordered the GTR CANBUS Lightning Series 2.0 3156 / 3157 LED Bulbs for my 2017 Mecedes CLA250 front turn signals. I received, I installed. Once I hit the ignition and toggled the left/right turn signals and emergency flashers I swore that I heard the Hallelujah chorus being sung. FINALLY, something that works without the hyper flashing error issue. The Mercedes electrical system is a strange beast but look no further, GTR Lighting has found the working formula.

i ordered these and 2 days later they were already arrived . i installed them and they look really nice. very bright

I installed the ultra 2’s in our 2017 F-550 and the improvement in light output is fantastic with no stray light blinding oncoming traffic. Fit and finish are top notch

Very straight forward to install, the 6K is better than most cars I seen. Lights are nice and wide, and covers a good amount of the road, and not blinding people ! I updated my whole 2016 Toyota Highlander XLE with LEDs, and this just topped it off !! Made the car look really nice !

Best headlights I've ever had! Like having the sun at your command

There are very few LED bulbs on the market that reliably fit in the front turn indicator socket of a 2017-2019 Super Duty. The GTR Lighting Armor Series 4257 LED is a perfect fit with a very bright amber light that matches well with the other amber lighting. I have been through many bulbs upgrading many vehicles and based on that experience, I couldn’t be happier with these. Thank you GTR Lighting.

They are amazing and would recommend to anybody!

Bulbs are so bright. I can’t wait to replace more.

Awesome quality

Bought them for a projector retro on my motorcycle and they out shine the halogens by far. No complaints. They look / feel well made and are very bright. The heat sink on the back seems to do a good job as well.
