LED signals staying on...resistors?

# Thread: LED signals staying on...resistors?

1. ## LED signals staying on...resistors?

Hey all. I know this has been brought up many times, but I have my own twist. I have both front and rear LED signals on my bike, and I need to know what size resistor to use. There are 8 LED's on each front signal, and then I have an integrator on the rear tail light (can't tell how many LED's). If I just use resistors on the front signals, will my signals flash? Currently they just stay on when I flip the signal switch (and yes, they ARE wired properly). If so, what size resistor? Let me know if you have a good solution. Thanks.

3. hard to sya without knowing what the current draw per resistor is

4. try a 6 ohm across the positive and negative leads on the rears. Oh and get at least a 1 watt.

6. we stock libertek adjustable resitors so you can make them flash at cuctom speeds

8. neat part kev!

9. so I tried the 6 ohm resistor (1 watt) and the signals flash at the proper speed now. However, it cause an equal, if not worse problem. The resistors are smoking and VERY hot. I'm on the right track, but how do I solve this problem? Do I need a stronger resistor? A smaller resistor? A different wattage? Any ideas let me know...these signals are becoming a plague.

10. try a resistor with more resistance. like 150 ohm and work form there

the higher the ohmage the better, or the higher the wattage?

12. wattage is max input voltage... this isnt changing anything to do with the bling, resistance is. you want a resistor that has a higher wattage than what you are using it for, amps * volts = watts

so imagine you had a 10 volt light that drew .5 amps, thats a 5watt bulb. so you would want a 6-8watt resistor, of undetermined ohms

substitute your numbers and figure out what you need

13. 50 watt and 6 ohm, very sorry, I was wrong

14. if you can't get them I can for 12 buck a piece, they are encased in an aluminum heatsinks and are fully gel sealed for complete weather resistance.

15. yeh if your resistors are smoking then i would say use a higher wattage resistor. the resistor basically turn electrical energy into heat.
