100w bulbs

100w on main beams should be fine on existing wiring. It already has relays in the circuit anyway. Check the fuse rating for the headlamps. A 100w main will take 8.5A per bulb.

better off with a set of spotlamps, if you want more light. and relays, of course :-)

but the existing wiring ought to cope. You might find that it doesn't quite get full power, depending on the wire used - older vehicles had sod-off fat wires to the headlamps which would take oodlesº of amps, modern ones seem increasingly thin, and probably less able to take uprated bulbs.

º like about 20.

Far better to fit decent bulbs - try Phillips Vision Plus.

I have had 100's in a 110 - the switch was fine - pity the multiplug on the bulb melted - - - - -

switch melted in mine, as a result of being a) old and b) required to run a pair of 55W spots as well.

replacement switch was OK though.

disco has been wired up with relays all over the place. dunno what half of them do.

They allow you to use a low current switch to control a high current load.

The other half do the same thing.

ho ho.

actually, what I were thinking is it *looks* (not fully traced) like whoever wired it for spots and fogs (latter not fitted ATM) has used 2 relays for each circuit - one under the dash and one in the underbonnet space. Brace of fused relays under the bonnet, one operates both spots and the other both fogs (I assume). 2 switches, one for each kind of lights, on the fuse cover panel, so you can optionally not have either set of additional lights on, which makes sense, and a pair of relays inside said panel as well.

What are you doing driving my Disco Austin?

That's more or less the way I have it wired at the moment, more due to changing the lighting rig and not bothering to re-run all the wires than anything else.

I did discover that the QT lamp pod puts out a lot more light when wired with 8AWG cable through a relay and breaker directly back to the battery than it does when wired with 32AWG back to a 20A fuse in the fusetray.

Didn't have flashing headlights fitted at one time did it? :-)

doubt it. yer never know. ICBA (and I'm too tight) to apply to DVLA for a list of previous keepers.

What's a keeper history cost in the UK? Just got one for my Series IIa here in NZ (cost NZ$12 = GBP4). 18 owners starting with the government Lands & Survey Department which probably explains why it appears to be partially military spec.
