Hello I have an 01 cav with no fog lights. I'v got a pair of bright driving lamps I want to only be able to be on with the high beams, still on a relay and switch but only want the relay able to switch on with the high beams. so I only have to switch to low beams for oncoming traffic. I have searched on here and found that the head lights use a switched ground which is fine. All I want to know is if the DRL's use the high or low beams. If they use the high beams I will have to do some rethinking. Thanks. Also can somebody tell me what size is the cooling fan fuse in a car with A/C.

DRLs use the high beam bulbs.

OH I guess I have some rethinking to do then. Anyone got any ideas? My Original plan was to connect one side of the relay coil to the High beam ground Guess that wont work .

With out disabling the DRL's Thanks.
