Is it normal for LED sidelight bulbs to pulse

[monty2000]

I fitted led sidelight bulbs today.
Canbus Error free ones.
Alls well but they pulse when the lights are not on
Is this normal as it looks like a police car?

A lot pulse for about 60 seconds after you turn the ignition off. It is the bulb "blown" detect system working, an LED bulb needs just a very little amount of power to work, and the bulb check thing suplies just enough.

They are pulsing with the engine running aswell though
And the lights off?

I know mine do it when i turn the car off but never noticed if they do it while the car is running.

Hello mate my ones do this also. So yes they all do it even more interesting when you put them in numberplate
