rainbow strobes
 

as in my avatar, rainbow strobes........... are they any good, rubbish, street legal.

do they aid visibility: is it easier for others to see headlight with it fitted :?:

As far as I know anything that stops you showing a white light at the front is not legal.

from all accounts aload of crap

I tried the rainbow strobes for the same idea that you have, to aid visibility(to be seen) and hopefully get the cagers to double take before pulling out (not suggesting you shouldn't expect this anyway). But found it restricted the light output to much at night time on the single lamp of my naked. Probably not quite legal but not sure about the yellow headlights of some years back, I think it was a French idea, suppose to give you better visibility(to see) in poor weather conditions.
I reckon any coloured filter will reduce the total light output unless you can increase the bulb wattage to compensate.
The best lamp upfront to get you noticed would be a flashing blue one – highly illegal.:twisted:

Chavtastic :roll:

:winner:

Yellow light to the front is legal....

.

Yellow or white, no others :!:

i wondered if they were a gimmick or actually helped visibility, sound crap and like you say most probably illegal. ta.

Not illegal if they come fitted to your work bike, although it does help being a police officer! :oops: :oops:
