Acquired the first of a few items from AliExpress the other day: LED license plate bulbs! (I ordered a few more things, will update this post as I get and install them.
The quality of the lights is pretty good, I'm impressed to be honest. Ordering from Aliexpress is always a gamble for me as I've heard horror stories of everything going wrong for some purchasers, but also good things from others. I ordered 4 just in case as well.
The only issue I've run into so far (that I was expecting) is upon installing, the dash had a "Check license plate bulb" warning. I googled around and eventually
found a post in this thread which alleviated the problem!
A comparison, OEM bulb on the left, new LED on the right. I'm really digging the crisp white colour of the LED compared to the dull almost-orange haze of the OEM bulb. Considering my GTI came with the lighting package and all the interior bulbs have been swapped out for bright LEDs, I'm surprised that the license plate bulbs weren't LED as well. Nevertheless, I am satisfied with how this turned out
Here's a night shot, they're super white and crisp and no errors so far!
