funny little lighting problem (wing mirror lights)

[travis]

Hi guys

Bit of a strange one here, ok first of all i thought i would change the little sidelight bulbs to the led white ones as imo the normal yellow light really looks wrong against the Xenons, all good although i get the check park lights warning but i can live with that.

Then I thought it would be cool for the lights under the wing mirrors to be more of a white brighter light (a bit like my old one series door handles)
This was all going swimmingly and the off side one went in and worked straight away! so i get to the near side one, take off the cover and replace the bulb to find that it flickers on when i unlock but then wont come on again and neither will the off side for a minute or so, went back to the normal bulb and all is fine?? why will it work in one and not the other? has anyone else experienced this?

ps I tried the bulb in both ways as i know it has a + and - and one way i get nothing at all, the other i get the split second on. I have also tried the led bulb in the sidelight holder and it works fine in there so it cant be the bulb either?

Its really starting to frustrate me now!!! do I need to change a fuse to a different rating or somthing? or would that make no odds? out of interest does anyone know which fuse the lights are on?

ok I hope this makes sense

thanks
