This question and answer came up on a site, which I was getting some information from. I thought that this would be a nice safety feature for our Deloreans, especially for those of us that drive them on a routine basis. I am far from being an electrical guru, but I know that there has to be someone on the list that might just know how or can figure out how to make this work for our cars. Is anyone willing to take on this project and sharing the information on how to do it with the list members. Robert Starling Vin#5252 Q: I see some of the new vehicles from GM have super-bright parking / turn signal lights instead of using the headlights as DRLs. Is there anything I can do like this on the Impala? A: Those lights actually use 2057 bulbs, which are dimmer both on low and high filaments than 2357s. The difference is that on the '97 F-cars they wire the turn signals to work as DRLs (not the parking lights), which means that the 32 candlepower bright filament stays on all the time. When you use the turn signal, those applications switch the brighter filament OFF rather than ON. In other words, if you installed the brighter 2357 bulbs in the F-cars, the DRLs would be even brighter, since they would be using a 40 cp filament instead of the 32 cp filament they use stock. You could get the same effect on an Impala if you wire the turn signal/park lamps so the brighter filament comes on with the parking lights. Also you would have to rewire the relay so that it flashes the filament off rather than on when the turn signal is used, just like in the F-cars. Then when you turn on the park lamps, you'd have the bright DRL style amber lights lit up just like on the '97 F-cars. That would also give you a "switch able" DRL, that is by using the parking lights you could turn them on. You could also wire it up to come on all the time the car is running. This would be an excellent use for the top Caprice wagon switch added to the LH side of the dash! If you have to have DRLs, the use of the turn signals would be preferable to the reduced power high beam headlights. They use less power, run up the hours on cheaper bulbs are much less offensive to traffic in front of you, plus they look better and more distinctive as well.
