I was initially a little reluctant to buy these lights as it IS quite an investment however, it so far is money well spent! I just installed my GTR Ultra 2 H11 headlights & I'm very happy! They are bright yet not 1 person put their brights on while I approached them! I've had the GTR Carbide Canbus 3157's & Reverse Lights for a few months now with no issues! Technical Support is SUPERB! My only hope is that they last a lifetime & Technical Support never waivers when an issue comes to light!

I purchased the red version of these for the rear tail/turn signals for my 2017 F150 XLT as an upgrade from the stock halogen bulbs. I purchased these because the description said they were CANBUS friendly and there would not be a hyperflash issue. The lights themselves are very bright for both the tail light and turn signal modes, but they definitely leave a bit of a dull area right in the middle of the housing. When looking at the entire light assembly from behind the truck, they put a lot of light towards the top and bottom of the reflector area, making it appear that there is 2 horizontal light bands, but the middle of the tail/brake light area lacks brightness. The standard bulb does not do this as the light output is more uniform throughout the entire area. When compared to the stock bulbs, there is definitely a huge light output difference, and the red is much more pronounced. Side by side, these LEDs make the stock bulbs look like a light red to almost deep orange color. I definitely have no complaints on the color or the intensity. What I do not like is the hyperflash in the dash. The bulbs themselves flash at the normal rate on the back of the truck, however, the dash turn signal indicator hyperflashes. I do not want to add resisters to the wiring, so I will attempt the ForSCAN programming option to see if this fixes the hyperflash. 5/5 for brightness, quality, and color, but 4/5 due to the hyperflash issue without other modifications (resisters or ForSCAN programming), meaning these are not truly 100% plug and play.

I purchased a set of the switchbacks for my front turn signals and two sets of the white bulbs for my tail lights/rear turn signals in a 2011 F-150. I bought these because I was under the impression that the CANBUS technology meant I wouldn't need resistors.

Switchbacks: Installed very easily and DID NOT need resistors (in my particular truck) to flash at normal speed. The white light is a little dimmer than I expected, but it does complement the color and output intensity of the SV3's I have for headlights. The amber for the turn signal is RIDICULOUSLY bright. It lights up the street signs two city blocks ahead of me.

White: Installed very easily and DID required resistors (in my particular truck) to flash at normal speed for my rear turn signals. The brightness behind the red reflectors is better than the stock/incandescent lights I had previously, but, again, these LEDs are a little dimmer than expected when looking at them through the lens. After telling HR customer support about the hyper flash issues, they quickly sent the appropriate resistors to me at no charge. The video found on the HR YouTube channel was clear and helpful.

Overall, these lights were worth the money, even though they were a little dimmer than expected.

Pretty bright lights
I like them

Bulbs do not work for a 2019 Dodge Durango GT AWD. Tried both bulbs and flipped the bulbs in the sockets. They don't even blink and gave a bulb out error. Emailed customer service the same day (January 13th) after waiting 13 days to receive the item. I has been six days (January 19th) and have not received an email back. I called during business hours and no one picked up.

Excellent LED, Perfect Lighting Love it for my Ram esp. for the switchback.
My Ram is a 2012 and did not have the switchback DRL. Headlight Revolution is also a great company to purchase from, I highly recommend them.

I am super impressed. Put them in my Toyota Tacoma. No complaints. Fiercely bright.

the brightest turn signals you will find. can still see them blink even even v.4 headlights are on high beam

First off the arent bright in parking light mode. Second why did i have to do someone elses jobs and remove part of the houses to make fit. 3rd and very important, why were they even sold to me for my f250? THEY DONT FIT THROUGH THE HOLE! Duh! for $70 and "professional" staff youd figure thats the first test to make. Sold the f250? So buy a damn housing to test your stuff before you sell it and have customers who end up doing your r&d. My 63k f250 isnt your shop truck.

I just installed these in my wifeÄôs 2014 Ford Expedition. She was having me replace the incandescent bulb on the driver side about every 6 months or so. I replaced those old bulbs with these. TheyÄôre extremely bright, and no hyper flash. SheÄôs very happy and she liked the way that they flash. This is what I will be getting when itÄôs time to replace bulbs in my F-150.
