I remember those early attempts at DLRs. Good idea but poorly done. The headlights would stay on during the starting process and then the alternator power surge would blow bulbs when the engine started. Now modern DLRs do not provide full power and bulb life is unaffected.

I had a 98 Buick with ddl's. When it was running there were always some lights on in front. When it got dark the ddl's would automatically switch over to regular headlights and the taillights would come on, there was a small hole in the dash with the light sensor. The manual showed which fuse to pull to disable the system so I could use the normal headlight switch to control the lights when I wanted them off or on, like at a drive-in theater.

In some vehicles just applying the park brake would/will turn off the DRLs. Both my Rangers with a maual shift were like that. The auto trans no.
Trivia time. All vehicles sold in Canada and manufactured after Jan 1/ 1990 have DRLs. My 1986 Bronco had them in 88 or so. I made a cheap simple system that turned the headlights on when I pulled the tranny out of the park position. Less than $10 and never failed.
