Hi

I was thinking to put some of these small LED Strobe Beacons, which are really bright but use no power hardly on the back of the Robey, just as a bit of warning really. I mean we do go 2 or 3mph so we are deffinateley not going slowly or anything! Wink

Anyway I want to be running off a 12v battery, what size?

I need a switch and would like them to flash alternateley, if you see what I mean, one switches off as one comes on, or vice versa, is that possible? I need two, one for each side, maybe one at the front, but that is not really important when it comes on etc.

I could also do with a light under the canopy be it led or a bulb with a switch that can be used should I need to see the guages etc after dark.

Now is it worth putting one of them sollar chargers on the roof when running, or at a rally to help keep the battery good before coming home and using them again?

Cheers

Dave

I think your simplest & cheapest solution is a pair of LED tail lights off a lorry & a 12V motor-cycle battery. A Lucas flasher unit might work if there's enough resistance 'load'. You'll get several hours of run-time on a full charge.
There are tons of LED units on eBay.

Personally, I'm not at all in favour of alternating warning lights - I don't think they are as effective - the local police, fire & ambulance services don't agree with this!

Just a thought, but would LED cycle lamps be any good? I got some a while back as backup for a dynamo set. Dirt cheap, highly visible (even during the day) and a couple of AAA batteries last for a LONG time, especially in flashing mode. Granted the mounting could be awkward - most rears are designed to clamp onto the seat post or seat stay - but I got an Oxford "carrier LED" on fleabay which although the supplied fixing was no good for my purposes had a couple of small bolt holes in the mounting plate, couple of small metric bolts and a home made adaptor plate later I had it sorted. I reckon something similar could be useful in all sorts of applications.
