reversing bulb replacment with LED bulb.

Hmm... Sounds like a RA thing..

Resistor goes across the 2 wires on each of the globes.

so what a 180 ohms resistor for each bulb?

SIR-VRX · Postby **SIR-VRX** » Mon Dec 07, 2009 8:48 pm

Try that. Otherwise it's a load resistor designed for LED lights. I have some if you want to buy one. $6 each + post. Not making any profit from that.

ok i will try a 180 ohms resistor first and see if that works. at the moment i don't even have any reversing lights. i put the stock halogens back in and they don't even work now. any thoughts on that?? have to get the computer reset???

Put them in & pop it in reverse, LED's come on ok but just turn off after 3-4 seconds!

Any ideas whats going on? something's not happy.

edit: this is the sucker:

the pic looks like it has a voltage regulator in it if that not working properly that may happen

the ones i bought are all forward facing and are 36LED. looks like it already has some type of resistor thingy in it? but yeh my stock bulbs aren't even working now.

Check your fuses Chris before you go too far

oh wow maybe your having an electrical problem with the ECU and or the contacts/relays but i think they are controlled by the ECU

ETACS controls the light system. But it is still fused

yeh the fuse was the first thing i checked and it's all good. i'm gonna take it to the mitsubishi shop and see if reseting the computer will fix the problem with the computer. than try putting in the resisor.

having the resistor in the thing doesnt have the load effect like a load resistor. a load resistor simulates as its called a load. so you get a 10W load resistor then its gonna simulatea 10W load on that circuit. becaues our cars monitor the lights to tell you if you have blown one the car things that the light it blown becaues there is no current draw from that circuit. thus the reason for the load resistor, you may have to do it anyway, but as far as i know only the tail/brake lights have this problem.

the computer may be thinking it has a blown reverse light, and turning off the power to it. (maybe why yours are going out) but i got no idea why its happenign with your stock globes now, maybe your ecu need to be reset (the self way)

whats the self way of reseting the ecu???

go to your battery and remove the negative terminal for i think its 30sec, but you have a security system dont you on the ralliart's so i dunno how it works with them. maybe ask adrian(SIR-VRX) first

chrisb · Postby **chrisb** » Tue Dec 08, 2009 8:07 am

yeh there is a security system. ADRIAN........

so i will just need one 10W load resistor for the two reversing bulbs cause they are in a circuit?? were would it go?
