Headlights

Does anyone know how to turn off my headlights with motor running and not the e-brake pushed. I blind everyone at the boat landing while un-loading my boat in the mornings. Oh its a 98 Jimmy, loaded,95,000 miles,vortec V6.
Any info appreciated.

Just apply the emg. brake a click or two just enough to turn them off.
Or rig up a toggle switch on the emg brake switch.
But remember the DLR is a safety deal and some places require them to be working on a public road or highway.

On 1998 you can disable the DRL's by removing the diode in the underhood fuse panel. The diode looks like a fuse, but has a diode icon on it. Removing the diode does not affect anything else, just disables the DRL's.

I don't know if the 98 is the same as my 2000 but if I push the dome override button four times in a row (turn dome off, turn on, turn off, turn on) a ding sounds and the lights go out. Repeat the procedure to turn them back on.

98 is not equipped with that feature. The park brake must be applied to the first "click" to override the DRL's, or remove the diode.
