anyone know where to get any after market tail lights or head lights for a 91 tercel toyota

it's a safety feature - why would you want to take it away?

The study I've read concerning drl's said that the lights make one see an approaching vehicle that they might not have other wise saw. Try driving at night with out lights and see how many other drivers won't pay attention to you because they are "used" to seeing headlights. Your common sense is flawed, one had better get used to paying attention to other vehicles if one is attempting to pull out into other traffic from a required stop. The real issue is, can a driver more readily see an approaching vehicle, with a cursory glance, if there is a light on on the vehicle? If comon sense can't answer this question, try riding a motor cycle in the day time with out a drl. Let me know if you get out of the hospital and can still communicate. I didn't walk away from my '04 Prius because it didn't have drl's, but it does have a headlight switch. Safety, Ray
