Default Heads and tails - lights...

Currently building a RXS100 something - hardtailing and new set of tins - as an experiment/ practice (first proper build).

I have a set of lights that I like but thier on the small side. What is the minimum head light and tail light size I can use?

They only have to be as bright as an approved lamp there is no size requirement.

But there are position requirements.

The should be E marked to be legal. There will be a number moulded on the lens.

For general guidence the US spec is good a reference..

Stop Lamp: A stop lamp must be visible from a distance of not less than 300 feet to the rear in normal sunlight.

Tail Lamp: Tail lamps mounted on the rear which, when illuminated, shall emit a red light plainly visible from a distance of 1,000 feet to the rear.

If you want the UK version... check this out

Only if you want to go for full type approval. MSVA is a bit easier so is UK lighting regs.

Check with Chris who is handilly stickied at the top of the these threads.

lenses dont have to be marked for MSVA or MOT

I made my own tail light for the latest chop, no marks on that, but all good

As my esteemed coleague Harry (and his not esteemed at all sidekick bert) says don't get tied up with the eurobabble it's for whole vehicle approval.

If the bike is already registered concentrate on things like can you see where you're going with the headlamp and is the tail lamp bright enough to stop vikki valium in her volvo ramming you up the jacksy.

Cheers

Chris

Extra bright bulbs then, its only a 6 volt system so not sure how to get brightness... Don't most LEDs work on 12 volts?

Technically LEDs work on 1.5-2volts. They are daisy chained together to work at the higher voltages. On of the disadvantages of LEDs is that when the volt drops below a certain level they just go out altogether. If you do go LEDs its worth putting a diode in series. Reverse voltage spikes will kill them, such as you can get during cranking or using the horn. You could always try doing you own LED lighting by buying individual LEDs and making up you own cluster. 4 in series should work on 6 volts. Use the hyper-bright ones for the brake lights

You could do worse than look here for quartz 6v bulbs he also does a 6v led stop tail setup

Smile aye.Lights

As above really.

LEDS are dead posh new fangled things. Wee little glow bugs on go faster powder,lol

Maplins are dead helpful and have a good range if you have one near you. One in Leicester is brill. They work the nerdy stuff out
