Headlight Bulbs

My MK currently has pretty dim headlights, looking at them they're 45/40w so I'm not surprised.

I believe the bulb type is p45t asymmetric like these ones: -

Is there any way I can increase the brightness without swapping the entire lamp units? I'm guessing I have to have that shape of bulb for beams etc as it'll be matched to the lens/glass etc, so what are my options? I don't seem to be able to see any similar bulbs with a higher rating.

It's a bike engined car if that makes any difference - could the builder have chosen these ratings because a bike alternator won't support higher ratings?

Ta, Sy

Be careful when increasing the load on the alternator. My old ZZR100 had these bulbs and when I sold it, the buyer uprated them to halogen bulbs and promptly burned out the alternator (which are very expensive)

are those bulb halogen type?

I've read that the bowls & lenses are shaped differnt for the 2 types fo bulbs.

you can get more efficient bulbs see

http://www.powerbulbs.co.uk/

now the rating is the same so does that mean they draw the same amps but more light or give out same light but for less amps; the former I suspect.

Make sure that you bulbs are wired as directly to the battery as possible i.e., no poxy switches in between; use a realy;

the headlamp stalk on ladrovers has small contacts that lose you a votl or so (I've measured it) maybe you have something similar; and that result is less power to bulb = less light.

When I had my FJ1200, the lights on that were pretty crap, so I went to the local bike shop, and got a Zenon bulb.

That was crap too, so I went and got a 120/90w, and stuck a couple of 55w spots on (with main beam).

These are ECU bulbs from the 1960s and pre-date the H series bulbs. Rarely seen now, BUT at sVc we have some specialist halogen bulbs with the base you have, so give me a call on 08 456 581 251.
