Festoon number plate leds

[AB5QTS]

A bit confused. Bought these Number plate LEDs

http://www.autobulbsdirect.co.uk/272-LED-Festoon-Bulbs-38mm-available-in-assorted-colours.html

Fitted them no bother, being the correct size etc. The left one didn't work at all when it did before and the right hand one which was out gave off a dim glow. Thought LEDs were either on bright or off?

Any ideas?

Cheers

Have you tried swapping the leds around to ensure they are polarised correctly?

ooooppsss clarification, removing it,swapping it end to end and re installing to see if there is any difference on each one

I got SMT type ones in both my S4 and the A6 and yes they will only work 1 way round , never seen them with a dull glow tho? I have had the style you have linked to but they didnt last very long in either car.

No I haven't trie to swap them end on end yet but I shall. Cheers

As said, will only work in polarised position, unlike standard bulbs.
