2021 Ram 1500 classic Warlock Easy to install, very bright, no flickering or error codes

Nice and bright

Cons: 0. (only one week in having them being bought). Pros: I love the 'orange-to-white' how it fades to the white. I have them installed on an 03 Accord Coupe; no problem with having them installed. Vehicle does have reflector lens but they do let the oncoming traffic know what you are going to do. I have purchased from SiriusLED Low Head Beams (they're bright) and with these LASFits on, you can definitely tell which way I am going to turn. P.S. They do (for me) hyper flash. I am awaiting my LM526 (LED turn signal relay) to correct issue

These amber LED bulbs did a great job replacing the amber WY21W incandescent rear turn signal bulbs in my 2011 Toyota Corolla LE (the Toyota manual doesn't specify the type of bulb, but the WY21W is what I found when I looked at the bulbs). These LED bulbs fit in my car's socket very securely, unlike some cheap bulbs. They have a nice amber color and are very bright. I also replaced my car's front turn signal/parking light incandescent bulbs (3457NAK) with the LASFIT 3157 3156 3057 4157 LED Bulbs, and they're all working great. The only problem I had was with the turn signals flashing very rapidly ("hyperflash") after going to these LEDs, and that problem was solved by using a GP-Xtreme electronic flasher relay to replace my car's OEM relay (GP part was marked "81980-50030" and "066500-4650" - the relay isn't listed as working with my car, but it worked after clipping the extra length of the two tabs on the bottom). (For reference, the OEM flasher was marked "81980-46010" and "066500-5541", and has a gray body with a blue socket on the bottom.) I went with the replacement flasher relay instead of using load resistors, which require tapping into the car's wiring and finding a place to mount them (they can get hot). The flasher relay was a real pain to change, but it was worth the hassle compared to installing load resistors.

Fit into the socket and work great. Matched my other drls and then are very bright with the brake pedal. They are designed and work well in place of a bulb. Durability is a matter of time.
