Micro relays are smaller if space is an issue. The original Siemens ones used by Guzzi from the mid 90s were rubbish though.

do a search "Pyro Dan" you get dpguzzi .com lots of info his relays quite simply work much higher rated than Seimens just about everyone at one time replaced all these on V11 lemans very quick delivery there are full specifications as well as parts x reference and pin reference there 

Make no mistake a full rewire is a big job, on top of the wires, connectors, switches, fuses, relays, shrink wrap in differing sizes you will need a decent soldering iron and good electrical solder along with good cutters , strippers and crimps then either different size sleeving a pull through and insulating as well as self amalgamating tape. I guess if you have time and patience it can be a task to enjoy .... but elektrikery can be extremely frustrating for the unwary just soldering up the 15 way mate n lock will test your hand eye co-ordination lol

Very unlikely it ever would.
But to give an extreme case, if you put a thin wire on a heavy current circuit, the voltage at the end of the wire will be lower, the higher the current, the lower the voltage. On a headlight, a 1 volt drop will reduce light output by something like 15%, so size is important.


True – I forgot to mention, that in that particular case, the "headlamp" was twin Cibie's with H4 bulbs and had its own separate loom, with relays and a fuse, connected directly to battery. Big smile
