Default LED rear lights

Right chaps I could do with a little help or advice. I'm no sparky so this might be easy for someone to answer. I went to fit my rear light's last night into my rear arches, and where they would be the wiring will be very close to the wheel (witch I don't like). So 2 option. 1 Modify my rear arches again to bring my current light out a bit to clear the wheel or slim LED lighting. So had a look around and found some nice rear LED light clusters. what is the story with needing to fit resisters to clusters? I have read that you need to fit a resistor to a single LED but I cant find anything on clusters so could someone help me out before I go buying some

Hi

If you are fitting led indicators you need a resistor otherwise they flash too fast.

If you are using mx5 electrics then scov had a work around which I used by removing on of the resistors from the relay

The details are on his build thread and were very easy to follow

I modified my standard Sierra flasher relay with a 100k potentiometer from maplin for about 70p.

Then turned it until I had flash rate that I was happy with

You only need to increase the load for the indicators. As said a resister inline or simply replace the flasher unit with an LED one!

Thanks for the info guys. But I have put a lot of thought into this and have decided to go with keeping the light's I have to match the others and to modify my rear arches as I have already got the gear around the garages, its just my time. Have a look at my pics and let me know you thought before I go cutting big holes in my arches.

Thank for the tip Steve that sound like a really good idea. Hopefully I will get into the garage to day and I will have a look. If it does work I will be able to shorten my pods a bit so they don't look so bad.

Has anyone got a link to the relay you are refering to? I have a mazda wiring loom and the indicators hyper flash. I have used load resistors which solve the indicator issue but when the hazard lights are in the side led indicators hardly light up. Any suggestions?

Thank you garyt. Is that a straight replacement or did you modify the loom for it to fit in?
