Volvo 242 Bulb Failure Light 1984

This is common, the sensor is very sensitive. Check that all bulbs match from one side to the other as it measures current draw differential and if it's off even slightly the sensor will trigger. Also give the sockets, bulb bases, and connectors a shot of DeOxit, and check the ground wires at the taillights.

Is the car automatic or manual? Around town or highway? 20mpg is a little low for highway driving, but typical of around town, manual will be 2 or 3 mpg higher than automatic in general.

Thanks James - the 20 mpg is around town. Highway is 22-23 depending upon how fast I drive 75-80 mph

I'll try the de-oxit. I an antique radio collector so I'm very familiar with de-ox.

Best regards,

Dave

And replacing bulbs at different times with different brands can cause problems. If all else fails, interchange the bulb or use 2 new ones.
