EwOkIE Posted January 19, 2010 Posted January 19, 2010 I stay in the UK and am looking for non polarised led, tried maplin with no joy and american companies want an order over £15.00 to ship them. Help please.
Speedshop Posted January 20, 2010 Posted January 20, 2010 LEDs by their very nature are polorised. Do you mean ones with a wide veiwing angle? These are commonly available in the UK. I suggest a proper electronics company like Rapid on line rather then Craplins. if you google LEDs there are many UK companies specialising in replacemets for vehicles. You'll find most indicators with a 'E' mark are viewable from the side, the veiwable section is covered by construction and regs laws so if they are legal (IE marked with an E mark) they'll have the required visability standards.
Gas up - Let's Go! Posted January 20, 2010 Posted January 20, 2010 LEDs by their very nature are polorised. I was wondering how a Diode can be non-polorised. Even went back to my old elecronic books, but no refference of such a thing anywhere....
EwOkIE Posted January 20, 2010 Author Posted January 20, 2010 Hi reason why I am asking as I fitted the LED's all round the bike, flash rate is ok just that they all flash at the same time like hazards. Dont want to fit resistors/diodes just to replace the dash light. As I took the bulb out to make them flash correctly just now. So dont have indicator warning light on dash at the minute. Thanks

Thanks Use a couple of rectifiers from a DT125mx or similar. Simple single phase rectification. Basically a big high capasity diode. Fit one in each feed then connect the outputs from the rectifiers together, connecting them to one connection on the dash lamp. Then earth the other wire to the dash lamp. The power cannot cross circuits anymore.Sorted. I know the DT is 6 volt but for a repeater lamp on the dash and the amount of time it will be on it should be fine. Cheap to. Edited to give clearer wiring inst.

Moderator Cynic Posted January 20, 2010 Moderator Posted January 20, 2010 Don't worry BWJ, My DT was banging nearly 18volts through my rectifier (oh missus) when the regulator packed up and that was fine. Battery wasn't so good mind .
EwOkIE Posted January 21, 2010 Author Posted January 21, 2010 Hi, dont want to cut into any wires or harness, just need the LED if anyone knows on where to get this in the UK. As all I can find is the US but they want a big order to ship them to here. Thanks

The non polarised LED won't help as they have little or no resistance so will still more than likely light all the indicators. With a couple of crimps you would be able to remove the rectifiers at a later date if you needed to. Or, why not use 2 ordinary 12v led's. Just put 2 of em in the dash lamp housing. One for each circuit. If you were really cute with the soldering you could fit them into a bulb base, after removing the glass etc. That would be a really neat soloution.
