I've bought them and used them, but not in vehicle applications 
except I have a LED unit for the sandbuggy.  I haven't gone over 
rough terain with it.  I had the K&N uinit with the LED bargraph and 
never experienced any difficulties.  My personal feelings are that 
the LED units are more rugged and less prone to vibration.  I've had 
one LCD multimeter that rode along in the tool box lose its display.  
The LED units do take more power to operate.
