new HIDs are a must!! Makes the R/T look so much better!
100x’s better and BRIGHTER. Cannot wait to see them at night. Very satisfied so far however cannot speak to the durability of them but impressed so far. Plug and play and no flicker so far. Absolute pain in the butt to install the headlights just because tiny little boy hands are needed but I got it eventually. The pic with the yellow circle is the new vs factory HID.

Works well once you get it in
These lights work really well and were plug and play. The light is very bright and seems good so far. The install on a GS350 was not easy due to limited space, but it worked out.

Good value
These lights were a perfect fit! I have had a lot of experience with inexpensive LED lights that seem to be a smaller or larger than the socket not these, they were a direct fit for my application. Lights are bright and after months of use still I have had no issues. The built in heat sync keeps them cool as advertised. Would recommend! Will be purchasing more soon!

work but stay "on" dimly randomly
These worked in my 2001 Dakota. Nice and bright, but not 5 stars because they tend to randomly stay on at a very dim low level after they turn "off" automatically or are turned off. I am assuming at this point the current draw is too low to really affect my battery life if the truck sits for an extended period of time. At least I hope so.

Excellent visibility, plug and play
Yes, I have a lot of experience using LED bulbs, and I can recommend them. They provide excellent light, are plug and play, and have an adjustment system (you can even out the beam), making them very convenient for different car models. The price and quality meet all expectations. I recommend them.

Just a generic bulb
The bulb size is like almost perfect. The fit was a bit tight in my 2016 Kia Forte5 SX dome lights but I was able to get them in with very little effort. They're plenty bright however they're nothing special. I bought similar bulbs from a different brand and when I compared the new bulbs to the old bulbs they were basically identical even down to the PCB traces. Overall I have no real complaints. The price was good and I got enough bulbs to replace the ones I got if they ever fail. Only issues where that the fitment was slightly not perfect but nothing that stopped me from using the bulbs.
