Red light mounting

[FROSTY:Me]

On a side note. Again not atacking anyone here because the intent is fantastic.
Rather than reinventing the wheel regarding rear light brightness and visibility why not simply use the law already in place for road bikes.

A lamp that is required to be fitted

must emit light that is visible within anangle of at least 15 degrees above and below a horizontal plane passing through the lamp, and within at least 45 degrees

either side of a vertical plane that is parallel to the longitudinal centre-line of the vehicle and passing through the lamp.

In plain english-it needs to be visible 45 degrees to either side of the centre line and 15 degrees up and down from horisontal

A clearly defined rule is gonna be a heck of a lot easier to comply with

It's probably worth a submission Frosty. You know how it all works.

And back to the previous comment about standard tail lights, generally they are now made of better stronger plastic (along with LEDs). Seems to be a no brainer really. given the pure number of half assed attempts using cheap push bike light (not made of quality plastic) it would seem common sence to stick to factory solutions.. I'm sure the entent of the rule was not to have rear facing red missiles...

Personally I don't like the use of RED Lights at all (perplexed when FIM required them in motogp and the like).
Last thing I'd want to see is a rider slowing down as it was mistaken as a red flag or in the case of track mounted red warning lights (which is a likely solution for the dropping volly numbers in the future).... High lux Blue/white LEDs (or micro xeon) seems to be a much more suitable colour solution.
Given most bikes now use LEDs its a simple conversion...

two issues here, one modern fairing panels omit the taillight mount so will present an issue and the other is if expensive tailllights that may not be on the bike when purchased or if you bin and break you're up for another.
custom tailpieces are another issue as is sidecars which are totally differnt
all it needs is some common sense really and not velcroing them on etc

Yip fair call.
I guess the point is it you can do it with what's already there. if not, then do it to a high standard rather than an after thought (5 dollar solution)....
I've got no idea what we are going to do on our old post classic chair (for next time I dig it out)...
I'll go and hide back under my rock.

Hear what you are saying but why eliminate the simplest solution as an option?
Im not saying it should be the ONLY option offered but why not let it be AN option.
Actually mon what I am saying is that the issues and potential issues with tailights have already been thought out over the last 100 years or so.
One issue already raised for racebikes is visibility to one side ot other of the bike -thats covered off already
the second that hasn't been mentioned is the light being too intense or focussed (ie LED's) and blinding riders behind--I bet this will be raised as an issue soon -again thats coovered of in existing road spec rules.
Again --NOT saying factory tailights it should be the only option-Im saying its an elegant and simple solution for a lot of guys.
Keeping in mind Im thinking about all the club level racers dooing winter series racing where this stuff will be the most noticed.

Few weeks late for this thread, but here's how a real organisation makes a rule:

This is the official MotoGP regulation for wet races and the red light

1.20 "Wet" and "Dry" Races
All races will be categorised as either wet or dry. A board may be
displayed on the grid to indicate the status of the race. If no board is
displayed, the race is automatically dry. The purpose of this
classification is to indicate to riders the consequence of varying
climatic conditions during a race.

When a race is declared wet, either on the starting grid or by
display of the white flag after the start, every motorcycle must
have its Safety Light switched on (refer to Article 2.7.17).
The Race Director may also instruct riders to switch on safety
lights by means of a board displayed at the finish line (100cm
horizontal x 80cm vertical, black background with the word
“Light” in yellow). Safety lights must stay on until riders are
instructed to switch them off, such instruction will be
communicated by the same board displayed with the word
“Light” crossed out.

2.7.17 Safety Lights
All motorcycles must have a functioning red light mounted at the
rear of the machine to be used in rain or low visibility conditions,
as declared by Race Direction. Lights must comply with the
following:

a) lighting direction must be parallel to the machine centre
line (motorcycle running direction), and clearly visible from
the rear at least 15 degrees to both left and right sides of
the machine centre line.
b) mounted on the seat/rear bodywork behind the rear axle
line and approximately on the machine centre line. In case
of dispute over the mounting position or visibility, the
decision of the Technical Director will be final.
c) power output/luminosity equivalent to approximately:
10 – 15W (incandescent)
3 - 5W (LED)
d) able to be switched on and off by the rider when seated on
the machine.
e) safety light power supply can be separated from the
motorcycle main wiring and battery

ACTUALLY, Spyda me old mate, there IS Velcro that is eminently suitable, as used in MotoGP etc - but its a safe bet that 99% will try and get by with Spyda pubes instead.

All that's really required is some common sense ....... oh wait, that's right ..................
