Rick, you're spot-on. After I get my eyes checked, I'm gonna learn to read. I completely missed the bolded part where he mentioned the bulbs he was using.rockin_rick said:When I read that he had 110W of foglights, I guess I assumed that he had additional/upgraded lights. The stock fog bulbs are 37.5W each for a total of 75W. Now I wonder... What's with the 110W juiced?
Also, thinking about the load of the fogs, I forgot that there is 2 wires going to each side, so the wire would only see half the load, which would make 5A, and 18AWG acceptable. However, there must be some point in the harness where it is just 1 wire (before the splice), and it must carry the full load...
If it is only 75W, then the load would be 6.25A (@12V), and 18AWG is OK. (FWIW - IMO, I consider 7A the max for a 18AWG wire.)
Rick
In my farting around with the fogs, I now run 50 watt bulbs in each housing. But I haven't run the lights for an extended period to see what would happen (overload/IR concerns). I think we can say that it could be worthwhile to upgrade the OEM wiring to get max output (I think some serious corners are cut with wiring-gauge choices in OEM form. Add 10+ years of wear and tear to said wiring and all bets are off). We agree about amperage ratings vs wire gauge too. I also like to fudge a little on the bigger (numerically lower) side to allow for degradation.
Rick, thanks again for seeing and addressing what I simply had missed.
