Question Repalced Fog lights but resistors get really hot??

On my 05 645CI I just replaced the fog lights but had to use the resistors so that I did not get a malfunction warning. It worked but the resistor gets really hot and there is nothing metal to attach it to. I am thinking of covering with black electrical tape and some heat resistance tape so that it wont melt the rubber?? Don't know it this will work but looking for other ideas or were to place the resistors. It stated attach to metal??

How big are your resistors? Are they about as large as a AA battery (maybe slightly shorter) and made of aluminum with small fins on them? If they are smaller that that or not made of aluminum then you may have under rated resistors.

If the resistors are getting too hot to touch I would find a metal bracket in the vicinity of the resistor and drill a hole in it. Then use a screw to attach the resistor to the metal bracket. The bracket will act as a heat sink. You can add thermal paste to help increase heat transfer if you want.

In a worse case scenario you could just upgrade to a higher wattage and higher quality resistor, they go for about $5. Look at the resistor to find out the specs (ohms) and then get one in 20-50W size for that resistance.

Here is an example 10 ohm 50W resistor on Amazon.

Thanks sorry it took so long to answer but it worked I was able to put them next to metal and found some heat resistance tape and now it seem to work good. Thanks again: rofl:
