I read that someone has fitted 6 volt LED indicators to their D7 & B175 Bantams. There was a link to a complete kit somewhere on the Forum but I can't find it. Any help finding a suitable LED complete kit appreciated.

Be careful when ordering those eBay 'LED' indicators. I bought a set only to discover that they are fitted with ordinary filament bulbs. As they were cheap as chips, I decided to keep them and ordered a set of 6volt LED capless bulbs.

I don't think you can buy a ready to fit 'kit' so you will have to order the individual components. I've just fitted LED indicators to my D7 and this is what I bought ( all from eBay)

Indicator set . (Doesn't have to be LED. 12v set is OK, just change the bulbs for 6Volt LEDs)

4 x 6volt LED bulbs.

1 x 6volt Flasher unit.

1 x Combination Dip/Horn/Indicator switch.Bertie-3in-1-switch-small.jpgIndicator-bar-small.jpg

I made the bars from 15mm tube, drilled, flattened and bent at right angles at the ends to mount the lights. The rear bar was mounted above the mudguard with pclips using the number plate fixing holes. The front bar mounted behind the headlamp with pclips using the fork pinch bolts.

The Flasher unit was mounted beside the rectifier.

Good luck.

Hi Ian.

I have sent you a message thru the  Facebook bantam site earlier today.

I understand that the kit needs to be 6v, with the replacement lens fitted.

Please advise me if you are satisfied with the end result,  using your new battery also.

TIA Terry

My d7 might be super one day !

Hi Terry. Can't see your Facebook message.  I just took delivery of the flasher unit today so haven't wired it up yet. However, I tested the LEDs with my new battery and they work fine except that I think that they are too bright and tend to wash out the amber colour of the lenses. I tried them with the original 6volt bulbs and they looked a lot better and certainly bright enough. I'll have to do some tests to see whether I want to keep the LED setup with the wishy washy lenses or revert to the nice amber colour of the original bulbs. It really depends on how much current drain I get with the normal bulbs. My battery is a 6ahc so should hold up OK. If worst comes to worst, there is enough room to fit a second battery wired in parallel to give 12ahc which should be more than enough. I'll update once I have some results.

Hi Ian, 

Thanks for your reply. My only thoughts would be the charge rate from the rectifier to the battery. The output could be effected by adding 

the indicators,  as the headlamp dip/beam brightness relys on the rpm of the engine. I hope it all works okay.

My d7 might be super one day !

You can get LEDs that are amber, which work much better behind amber lenses than white ones. 

I imagine that an intermittent 40w load from incandescent bulbs will cause the head and tail lights to flicker in time with them at idle, particularly if the brake light is on at the same time. 

A number of years ago I had a TZR 125 that suffered from that issue really badly, and it was cured completely with the use of amber LEDs in the indicators.

I agree that amber LEDs are the answer but I looked high and low for 6volt Amber capless LEDs and was unable to find any until today when I discovered that 'Classic Car LEDs' supply yellow LEDs that work on 5-12volt, Pos or neg earth for only £0.57 each, so looks like the wishy washy indicator problem may be fixed and I won't have to worry about the problem of current drain associated with incandescents.

You do realise those 59p LEDs are car dash warning bulbs,
and are a 286/T5 fitting and only 25 Lumens (measure of brightness) led flasher bulbs are around 300/400 Lumens

I wasn't going to say anything, but now he has. laugh

I wondered what these indicator bulbs were, for only 57p, so went to the web-site .....

I have spent some time looking for indicators to put onto my D1 – I soon found out there are a fair few feeble (cheap) ones out there – the current plan is for bar-end indicators but to get the brightness I want in daylight are going to have to be 12 Volt – the best don't exist in 6 Volt .....

It's one of those apparently simple jobs that turns out not to be not so simple ...
