My question is; is it road legal to fit lamps that low and can anyone foresee any possible contraventions of the Road Traffic regulations?
As you might expect, the UK Law / Regulations are not easy to comprehend.
My interpretation ( not tested in any Court of Law so use at our peril ! )
is that if you follow these guidelines you "should" be OK ! .......
If you are fitting these to be SEEN rather than to SEE with,
then they would ( probably ) be classed as "Front Position Lamps"
Relevant information is drawn from the UK Driver and Vehicle Standards Agency publication,
"Motorcycle Single Vehicle Approval ( MSVA ) Inspection Manual."Section 6, Annex 3 on Page 57 in respect of Front Position Lamps states that a Minimum of 1 must be fitted.
There is no maximum number stated so additional Front Position Lamps are permitted.
( They must be fitted to the Front of the Vehicle ! )
The lamp colour must be white and a "Tell Tale" is required - i.e. for the Manufacturer's Position Lamp,
there is a Lamp symbol on the Instrument Panel when they are switched on -
If additional Position Lamp(s) are connected to the same circuit, no additional "Tell Tale" would be required.
If additional Position Lamp(s) are on a separate circuit / switch then an additional "Tell Tale"
( such as an LED built into the switch to show when it is switched on, must be incorporated.
The minimum mounting height from the road surface is 350mm, and the Maximun height is 1200mm.
All Lighting fitted to a vehicle shall be "EC" approved and marked as per ECWVTA Base Directive 93/92/EEC.
Lighting fitted to a vehicle, whether compulsory or optional should be maintained in good working order
as per Regulation 23 of the Road Vehicles Lighting Regulations 1989.
