CamChain Posted January 1, 2011 Posted January 1, 2011 Hi all,I'm installing a rear light, stop/tail with integral indicators, on the bike. It's an led unit. Now I have read that resistors should be connected, in line. How would I know the ohm's resstance I would need, or is there a standard resistor for the job? any help appreciated. Quote
Guest Posted January 1, 2011 Posted January 1, 2011 Got a feeling the resistors are readily available from all good bike shops. HG stock them for sure. Quote

I take it that the resistors are a standard resistance, no need to work out the resistance. Just been looking at them on fleebay. Do I still incorporate the flasher unit, the stock one, or do the resistance units take care of that. Quote
Guest Posted January 1, 2011 Posted January 1, 2011 Never fitted em mate. But I believe the existing flasher unit stays in place Quote
Hoover Posted January 1, 2011 Posted January 1, 2011 get yourself an LED flasher relay from halfords then you wont need the resistors. Quote
medtec Posted January 2, 2011 Posted January 2, 2011 get yourself an LED flasher relay from halfords then you wont need the resistors. agreed costs 19.99 and u just unplug one and plug in the other well thats how it worked on my ninja when i fitted the integral rear lights Quote
Stu Posted January 2, 2011 Posted January 2, 2011 forget the flasher units they rarely fit properly and are usually poor quality and are made for LED lights front and rear so may not flash at the correct rate if the fronts arent LED hein gericke sell the right resistors at £2 each i have the same type of light unit on my bike and the resistors work spot on Quote
CamChain Posted January 2, 2011 Author Posted January 2, 2011 Decided on the resistors. A fiver for 2 with wiring. I will be getting led's for the front, but most of them come with the resistors.Thanks for the assistance lads. Quote
medtec Posted January 2, 2011 Posted January 2, 2011 Yeah i should of said i fitted led flush lights to front at same time so the unit worked for me no issues Quote
Guest Posted January 8, 2011 Posted January 8, 2011 The indicator circuit will need resistors, the stop tail light circuit does not.http://img.photobucket.com/albums/v728/marsey0/Resistor_wiring_diagram.png Quote
Guest Posted January 8, 2011 Posted January 8, 2011 If you need to buy one: the formula to calculate the resistance is R = (V*V)/P, where V is the battery voltage and P is the power you want the resistor to draw.For a 5W load at about 13V, that works out to about 33 Ohms.Bear in mind when installing, that it's dissipating the same power a normal bulb does, so it'll get hot.

CamChain Posted January 10, 2011 Author Posted January 10, 2011 Some very helpful info there lads. Not only will it assist myself, but also others. Nice diagram Quote
