I am still on that same tank of gas. I am estimating 1-2 MPG loss from the lights. I would rather be able to see at night though since the deer around here get pretty large. One accident with a deer would total the car and I would end up driving my 14 MPH 4X4 again. No thanks.
These lights were offered on 1995-2001 3 and 4 door models depending on trim. I think all 1995 models had these bucket style lights.
