Re-worked Harley tail light
 
We all know that bike building/styling is subjective - one of my biggest dislikes (putting aside any 'safety' arguments) is pokey-out indicators.

I tried to find a standard fitting Harley tail light with incorporated indicators, but couldn't find one that I liked the look of, so I bought this from China:

and reworked the LEDs to get this:

I've fitted it onto the standard back plate, and added a waterproof connector:

A couple of shiny load resistors under the seat, and it works like a charm - well cuffed! :thumbsu:

Sorry to burst your bubble but the light is not legal for the mot
When duel purpose lights came on the market for sports bikes I phoned vosa to check and they was unsure this was probably 4 year ago . But last year they decided that they are no longer legal for the mot because they inter act with the rear light/ stop lamp . Also they are to close to each other.
Their is however a Harley light that is ok from what I understand the rear light/ stop lamp is built in the indicators ( one on each side of the bike ) these are ok because their is a large gap between the lights

Thanks for the advice - as usual, the message is never clear from the powers that be!

Before I started it, I checked with our local bike MOT place, and was advised that there was no minimum distance and no minimum size, only that 'discretion should be used' and that the biggest concern was visibility. I've used Pirahna superflux LEDs, so visibility shouldn't be a concern - I guess that I'm now in the lap of The Man! :)

I've not altered the sub frame or rear fender mounts, so I can revert if needed - I'll just have to keep the pink bits crossed!

Just to be clear - the actual LEDs don't perform both tasks - I've removed the outer points from the tail/brake circuit and replaced them with amber LEDs on a separate circuit - the only part playing a dual purpose is the actual housing. Here's a pic without the turn LEDs lit:

It's typical vosa I get it most weeks at work .
If your guy is happy to pass it and your happy to use it carry on at end of the day most police prob don't know the right answer .
You might get a defect form if pulled . Which is a easy fix :-)

HardShoulderShoe 07-08-2013 02:10 PM

Cheers bud - I always appreciate the advice - I'll chance my arm and see how I go on!

harry 07-08-2013 07:33 PM

As a non typical VOSa man, I can tell you that the MOT does not test the separation of indicators only that they work and are not obstructed or affected by another lamp.

However the minimum separation is part of the UK lighting regs 1989.
http://www.legislation.gov.uk/uksi/1...chedule/7/made


And this does state a minimum separation, as does MSVA which is based on the lighting regs.


240 mm for rear indicators

The regs are decided by governments we just enforce them.

John Hopkins 07-08-2013 07:38 PM

I have to ask..just for the devil of it..but why do you need indicators on a bike?

John.

HardShoulderShoe 07-08-2013 07:38 PM

Well that's perfect - if you stand REALLY close, they're well further apart than 240mm! :)

So that when you press your remote alarm fob you can find your bike? :p (Most useful in motorway service stations providing you are on the correct side of the motorway)

HardShoulderShoe 07-08-2013 07:55 PM

I also find them handy to hang stuff on. Although I may have just discovered a flaw in my 'hide them away' plan...

True we don't test the distance apart.
But I do remember reading it in matters of testing and the width was mentioned but the fail is under interaction with another light .

gothtec 07-08-2013 11:10 PM

Cant stand LED indicators integrated with brake lights....

You cant sodding see them sometime and buses have now started using them

Stubborn as I am, I'd argue the point, as the there are three entirely independent circuits in there - one for the brake/tail, one each for the indicators. I've used all of the original wiring, but instead of filament bulbs, there are LEDs and resistors. It's no different to a cluster on a car. :-)

Still, I always appreciate the warning!

Like I said right at the start, it's subjective - I never really use them anyway, I much prefer a MASSIVE 'hands out, you can see me' stare, from the old days when the indicators were the first casualty of a chop project.

Aside from that, this Pirahna superflux LED's are ridiculously bright, and very hard to mistake - not like some of those dodgy manufacturer fitting candles. :D

John Hopkins 08-08-2013 10:01 AM

A good bright flashing light draws the eye, but if they are too close together the following vehicle can be confused as to which way the biker intends to turn..maybe a flashing arrow could be made from the same leds, but it still seems a bit small to me..I can see the point of the law on this one..

I can't see the point of the law that says if my bike is registered in July 1986 it is safe for me to ride without indicators and if it is registered in August 1986 it is not..

I had considered an arrow formation - anything is possible with the configuration of the LEDs as they are - but I'd always back it up with hand signals and a clear 'intentional riding strategy' to be sure. I've been knocked off a few times with stock indicators blazing away - the only practical solution (aside from a massive bat with which to beat the offender to a pulp) is awareness and preparation IMO! :-)

spacing for indicators is 240mm for the front indicators
only 180mm for the rear ones
minimum height of 350mm and a max 300mm from the rear

:cool: of course I am quoting you MSVA regulation

Taff 16-08-2013 10:11 PM

Fuck the regs and the intricacies of the law, god we'd all be riding bog stock bikes if that insipid attitude was followed to the letter.
Brilliant job, well done that man.

agree 100%, was just adding to what was said above:thumbu:
the unit does look good too

Thanks Taff - from you, that's a massive compliment. :)

I like what you have done, great idea.

Wonder if the same could be done with the smaller Sparto style light I have on the back of my FXDB. Don't like the separate indicators and was thinking of doing something about it over the winter.

If you send me some pics/sketches of what you want, I can give you an idea of what would be possible with LEDs...

I have other ideas for mine too, like getting one of the halo style headlights and working indicators into that. It seems there are already 7" versions, but the smaller ones seem to be thin on the ground.

HardShoulderShoe 18-08-2013 09:37 AM

It might be an option to use something like this:

http://i.ebayimg.com/t/Black-LED-Tai...Lbz!~~60_1.JPG

Fitted underneath the main tail light, wired to work in conjunction. Probably wouldn't require load resistors or other wiring changes either.

PS. I think there is a chrome version too, if you don't like black plastic (eww). Although personally, I'd rather strip it and paint the black plastic.
