That makes perfect sense thank you! So what would be a good setup if I wanted run a led? I want something where I can just replace if it goes out like you were saying earlier.

So what you’re saying is it’s just like a stock headlight but you can replace the bulb whenever you want but you have to buy the brackets to hold the bulb in?

No brackets needed... look at the Pobit sealed beam option on ebay. It comes with wire clips to hold the light into the rim like the later models. Clips are #10 in diagram.



I like the MikesXS clips... looks like they are out of stock... you get 5 and I usually destroy one or two which leaves me the three left I need to hold the light in place.

Over the years Yamaha appear to have switched between sealed beam units and ones where the bulb could be replaced. An awful lot of the early models were fitted with lights manufactured by Koito.

What I did was to scour ebay on a regular basis looking at all old Koito units and also Yamaha headlight buckets with YHA107 stamped on them. I ignored which model the vendor stated that they were off because a) many owners chopped and changed parts and therefore the bike that it eventually came off might not have been the bike that it was originally fitted to and b) many parts were interchangeable between models. I had to pay very close attention to the location of all of the mounting holes and also the long adjusting screw. I did make a couple of errors along the way though!

As I understand it, the spring mounting clips (that hold the glass inside the chrome headlight rim) on the aftermarket lights replace the small screws on the original headlight that did the same job.

I can't help with led lights I'm afraid, as that's well beyond my skillset!

All the best and good luck with your search.

So I can change bulbs out on this one? All I need it the clips? And would I be able to run a LED?

No, the pobit lamp is sealed beam, just like your original.

Not sure what "this one" is... the one in post #12 has a replaceable H4 6v 35 watt halogen bulb...

There are many replaceable bulb H4 reflectors like it to choose from. Most have no bulb (sold seperately) or a 12v 55 watt bulbs so you also need to get a 6 volt 35 watt bulb.

Yamaha headlight runs on AC power. LED's need DC power. I have not seen an LED that will work unless you change the system to DC power.
