Last night ride out with my Son he was behind on his modern Triumph on main beam so i could see where i was round the lanes,just had to really slow down when someone came the other way and he dipped,like turning the lights out. scarey hence the update.
Cheers guys Rich

Rich, as Bryan says they are a standard fit for 7inch units and there are alot of choices for the car guys out there that ask the same question about upgrading for things like the original mini, escort mk1, triumph and land rover as a good scource of newer kit to suit.

Often done on older rally cars was to feed the headlights etc straight from the battery via a fuse and then use a relay turned on and off by the original switching tom make sure the correct amps could be supplied and make the most of 60watt halogen bulbs.

I'm guessing that's not required if you run led lights though, does anyone know if that's correct?

I think Goffy does some 45/40w H4's as a reasonable compromise. http://www.norbsa02.freeuk.com/goffybulbs.htm

You might want to think about replacing your binnacle lights with LED's to reduce some of the load on the charging system, but that's about it. I would shy away from replacing headlights/taillights with LED's. As far as I'm aware, the UK legality of these LED units is still very grey. Also, make sure your wiring loom and contacts/connections are clean, properly seated and in good nick. I asked much the same questions myself when I first showed up on here and that was pretty much the sage and sane advice I was given. There's plenty of searchable discussion in the archives about this on here and over on the US site.

I understood that the LED front lights fitted by car manufacturers are driven at something like 400% of their rated spec. Because this would ordinarily overheat the led unit, they are pulsed like a strobe light at a rate you can't normally see so they look continuous. If you see some slow-mo footage of them on something like top-gear you can see them flashing.

It doesn't look like any of the straight bulb replacements would do this, so interesting to see if anyone buys and trys an led "bulb".

I've always run CB750s with Cibie Z180 and 55/60w halogen bulbs with no problems.
