I know there are two relays in series: #1 is on/off, #2 is dipped/main and (from memory) it's the dipped/main one that tends to die. They are in the fusebox in the engine compartment, front LH side, and I have a feeling they are Toyota specials - certainly they are a bit of an odd shape.
I didn't investigate them since the relief harness I made just uses the original Toyota relays to switch a second (new) set, so the original Toyota wiring is now only carrying the load required to switch the relays - probably less than an amp.
I've spent about an hour trying to track down the law on headlight bulb wattages, and failed completely. As far as I can see the headlight and bulb makers have to meet all sorts of rules about light spread and overspill to get their "E" mark, but nowhere in ECE 48 or the UK regs does it mention anything so plebeian as watts.
I can only assume that there is some sort of tacit agreement between manufacturers and legislators that it should be limited to 60/55w for cars ... and then they bust a gut to get more out of that limit with the "50% brighter" stuff etc. Interestingly the limit for lorries (24v bulbs) seems to be 70w.
Ho hum .. bed-time!

Christopher,
As I said I don't know about the relays, I would need to look for
a rating on them. Are they standard pin configuration?, if so it would
be easy to drop in proper relays. I wish I had the time and light to
check.
I also thought I had seen a bulb wattage specified.
Regards,
