iJDMTOY Xenon White 54-SMD 7507 PY21W Canbus Replacement Bulbs Compatible with BMW 1 2 3 4 Series X1 X3 X4 X5 Front Turn Signal Lights or Rear Backup Lights

EXCELLENT PRODUCT SHINES A LOT!!

Normally I'm lazy enough not to write reviews, but I just installed this product on my 2013 VW Tiguan today and couldn't resist to give them applause . Man, these are awesome. No error code, brighter than the original incandescent bulbs, sharp response. Literally plug and play as it's described. If you're looking for an easier way to upgrade your blinkers, this is the right product for you.

One bulb was the wrong bulb so wasn’t able to use them right away they did send me a replacement bulb free of charge.

Disclaimer: For anyone complaining about flickering upon startup, hyperflash or occasionally while driving, please know, that is exactly what should happen. The ECU in your vehicle has been coded to expect a halogen bulb and to monitor that bulb for outages. It does this by sending small pulses through the circuit to detect a short. It does this at startup and while moving. This is what illuminates the "Bulb out" warning.In order for your installation to be considered truly complete, you will need to code your ECU to expect an LED bulb and to turn off the cold and warm bulb monitoring. For those with a BMW, get the Bimmercode app, buy one of their supported OBDII adapters and use their EXTREMELY USER FRIENDLY app tool to do so. It takes approx. 10 mins from start to finish and you will be 100% satisfied with the outcome.Onto the bulbs themselves, they are exactly as described and are an order of magnitude brighter and faster than the P21W halogens they replaced. Within the reflector housing of the F30 headlight, this makes for an awesome marker and indicator. As for longevity/quality, I will update this review over time. Any hiccups I experience will be outlined here.If you are want powerful, fast LED lighting at a fraction of the cost of some of the alternatives, I'd say buy these and call it a day.

I got the product very quickly. I have a 2014 BMW 328i (F30) and it worked perfectly. 3 or 4 other bulbs I tried threw error codes but this one never did. It’s also REALLY bright. Reasonable price and exactly what I wanted.

Plug and play! 0 errors! I am using these as turn signals/park lights in my 2015 328i. They match my halo's perfectly and give my car an aggressive look when I run them as park lights. I am super satisfied with them!

The lights have good brightness, not too blinding bright like another light I purchased from the same seller, and not too dim like the original halogen. They are not amber color though but sort of yellowish green when coming out of the reflector housing, just weird color . I'd have kept them if they were amber color to match the rest of the lights in my BMW.

Great starting spot for someone looking to work on their own car and mod it

These bulbs look great. I was worst first whether they were compatible with my car as they threw an error code every time I started the car.BMW X4.I realized that the car needed to be coded to let it know LED bulbs had been installed instead of regular incandescent.After coding, no problems
