## Customer Reviews

### ⭐⭐⭐⭐⭐ Stopped the Flickering
*by J***N on February 28, 2024*

2006 Jeep Commander. I added LED bulbs which worked fine, but would flicker dimly after turning lights off. These resistors eliminated that issue. Not fully certain how, but they definitely worked for the issue I was having. And the price is right.*EDIT AFTER A YEAR*Still work perfectly. Listen, don’t pay any attention to the dummies who complain that the car almost burned down. However, you DO NEED to follow the instructions and mount them to a metal surface. They need to shed heat into something metal. If you just let them hang out, they can’t transfer any heat anywhere, so they will continue to get way too dangerously hot.The mounting tabs are a little too small for any screws I had on hand. I used heat transfer cement instead to glue them to a metal radiator support. Thermal glue, whatever it’s called. Greyish stuff for $5 for a couple tubes. Worked perfectly and still holding strong with zero issues.I used a total of four resistors, one for each high and low beam bulbs. I didn’t need them for my fog lights, because they don’t go through the fault code system, so no weird error or flickering.

### ⭐⭐⭐⭐⭐ Does not fit 2020 Tacoma offroad
*by M***H on July 21, 2025*

Super happy with the harness..but 100% will not fit 2020 Tacoma even though it says on description. So I cut the sockets off and used quick connects with oem plugs. Still works great. Sucks if you don't want to cut oem wires for a Tacoma. I really didn't want to. The sockets just don't fit. But the harness is solid.

### ⭐ Re-vamp your product.
*by C***S on February 26, 2022*

PROS: The product works.CONS:1) The bulb was very difficult to put in. I had to use the other end of the harness to "break in" the bulb socket on this harness before I could get the build to go in. Seems like the plastic is so rigid that you almost break your LED bulb trying to put it in the bulb socket of this harness.2) The wires are WAYYYY to short to mount the heatsinks where they need to be. There is a warning(that comes with all resistors) to not mount then on our near plastic, because they get extremely HOT. Because the wires are so short it makes it almost impossible for the average "diy'er" or even a more experienced person to mount then properly. I'm a certified professional installer and I found these wires ridiculously short. You shouldn't have to remove a light assembly completely to mount the heatsinks or modify the short wiring (which will void any type of product warranty) to make this install work.Unless you really know what you are doing, I don't recommend these harnesses for you.To the manufacturer. If you read this review. Add 2 to 3 more inches of wire. It won't break your company. He[[, charge a dollar more for the product. It would be worth it to help you target audience have an easier install and reward you with better reviews.
