Rear light/stop combination?

[RyanTZR125]

I want to get rid of the separate stop lights on my H100, I've got bullets, 2 for the stop lights and one for the tail light. Is it possible to wire the brake lights to the tail light and replace the bulb for a dual fitment, creating a single stop/tail light? or is that not possible.

I've seen the bullets on ebay, that are dual bulbs

And the 6v bulb I think i'd need.

just use the stop/ tail light off a CG?

mine is a combined brake an tail light

I'm a tight twat, If its a case of just re wiring and changing the bulb for a dual fitment, then I'd do that. If that's not possible, I'd look at re placing with a suitable alternative

nowt wrong with a being tight mate

yeah you should be able to use a twin filament bulb i reckons....

or....

clicky

ahh i see your bargain hunting skills are better than mine!!

You can't use a twin filament bulb in a bulb holder that is designed for single filamet.

It may however have a twin filament bulb in already, and not have the brake side wired in.

Well a single filament bulb won't go in a dual filament holder, due to the offset pins being different, and the contacts.

I've converted an H100 to 12v this week, so I'll be running a 12v LED tail light in that - if you can find a 6v LED stop/tail, that would be perfect for saving power, and making your headlight a bit better!

Fitting it into the casing would be the hard part, but theoretically possible. Piss easy to convert to 12v from what I found this week (at least for an H100A it is) -

1) get a 2 phase, 12v reg/rec off a shitty chinese scooter
2) connect the generator wires to it (the wiring colours even match the shitty scooter reg/rec),
3) fit a 12v battery from an early CG125 and connect battery wires to regulator (connect the battery to the loom as normal, in addition to regulator wire)
4) take the rectifier diode out
5) disconnect the pink wire to the ballast resistor
6) connect a black wire from inside the ignition switch, to the yellow wire that goes to the headlight switch,
7) replace bulbs and horn with 12v versions
8) Ignore the fact it has a 6v coil and CDI, these seem unaffected by the overvoltage - I'd been running them with the genny pumping out 20v for quite a while - that was the reason for the 12v conversion (I'll find out what happens long term when it's been used a bit more)

You make it sound so easy

Looking closer at the bullets it seems the top one is a dual fitment, with a single filament bulb fitted into it, the bulb holder has two connection points, where as the other two (Brake lights) have a single connection point, but all the bulbs are single filament,
