Not a lick of sense to me.What would a few amps of headlight current do to warm a battery that a few hundred amps of starting current would not? Maybe your BIL is the GM engineer who designed GM's running lights on their pickups and Suburbans. You know, the ones running up and down the road with only one light working.:laughing:
Makes no sense to me either.
Instead of the woed "warm", insert the word "drain" and it makes perfect sense.
Because that is all it will do on a cold winter day. Help to drain the battery faster.
Allthough if it is indeed true, Maybe in the winter I'll start leaving my dome light on. That way the battery is already warm the next morning when I go to work:laughing:
Clinton did that to us DRL that is.
