Hi everyone. I have a mk3 Leon FR and am looking at upgrading the indicators, reverse, rear fog and DRL/sidelight bulbs to LED.

The bulb types I need are:
P21w (2x for DRL and 1x for reverse)
PY21w - Amber (4x for indicators)
H21w (1x for rear fog)

Does anyone have recommendations that will avoid any warnings that may appear?

Kind regards,
Joe

@Kr00Lik Buy some "hyperflash" LEDs, they are the brightest I have come across so far. They also dont trigger any warnings in my Leon. You can find them on Aliexpress

I created a POV guide for the rear indicator bulbs

Plus if they do trigger warnings, those warnings can be coded out BUT this is not recommended if it can be avoided.
