Whilst the car was in the garage getting its stereo changed I also took the time to replace the interior bulb with an LED.
I got these in the mail the other day because they are shorter than the ones I had.
Its a fairly easy install. Just got to be careful taking the lens off (it just pops out if you gently lever it from all sides) and then taking the bulb out (its very recessed and a pain to get at). Pop the new LED in and away you go. Easy as ever and the results are great.
