After 6 years, plus whatever the previous owner got out of it, one of my
headlight bulbs has packed up. A quick google tells me things have
changed since I last had to buy a headlamp bulb. Prices seem to be IRO
£7.50 for a single decent bulb
http://www.autobulbsdirect.co.uk/H7-...b-OSULTH7.html
and the websites are pushing 'xenon upgrades' such as "H7 OSRAM Night
Breaker Plus +90% More Light 50% Improved Life Upgrade Xenon Headlight
Bulbs (Pack of 2)" for £27.50/pair
http://www.autobulbsdirect.co.uk/H7-...-NEW-pair.html.
Also there is a "HID Kit"
http://www.autobulbsdirect.co.uk/H7-...rsion-Kit.html
for over 90 quid and comes with what they call a "ballast" that looks
like a high votage converter.

Any thoughts on these 'upgrades'?

I thought the Xenon headlights needed to be self-levelling, and that they
were starting to check this at MOT from this year? Certainly the retrofit
"boy racer" ones seem to be the cause of most of the dazzling ones ...


Be careful here.. xenon bulbs are just tungsten halogen bulbs sold at high
prices to mugs that don't know the difference between HIDs and tungsten
bulbs.

Then there are the blue coloured ones that are sold at high prices to the
mugs that want others to think they are HIDs.

Tungsten bulbs come in different types including, normal, long life, high
output and silly blue.
50% more output doesn't double the range you can see. In reality it makes
no difference to dipped beam as the output isn't the limiting factor.
