Celica Forums General Discussion Exterior question on LCD kit

is there any way to just light up the gas/temp instead of the gas/temp and background...

no...because it's a screen that the LED are lighting up...it would be impossible unless it was manufactured like that.

I don't understand this. The stock gauges are not back-lit; only the gas and temp gauges light up.

The pics I've seen with red LEDs are the same way.

Example:


It seems to be just the blue LED conversions that have the entire LCD gauge backlit. Is this true, and what causes the difference?
