Re: Changing Front Sidelight Bulb
The bulb is a H6W, and costs about £5.00
There are quite a few threads about changing the side-light bulbs,
some people have had a nightmare doing it, others can do it easily.
I had to change mine recently and followed the advice from various threads to use a mirror to see exactly what you have to do, and be patient and gentle when removing the bulb to ensure you don't snap the elongated plastic bulb holder,
The rear cover is a bit fiddly to remove from the LHS light-unit, but again patience is the key.
Alternately, pay someone else to do it, and watch for a good laugh
