Re: 11-13 VLED 3157 DRL 5k
Some cheaper 3157 LEDs have a different base (a deeper round section) which stops them pushing in far enough - if you compare the base of the LEDs with the standard bulb you can easily see if they are different.
There is no fix for this issues apart from ensuring that you buy the correct shape base the next time.
