(If this appears correctly) it should be ÂµA but it's quicker to type uA. Answer: UA stands for Urine Analysis.. When you pee in a cup and the doctors take it and analyze it to see if you or whoever has done any drugs or drank any alcohol in the past two weeks. Microamperes. The u is the closest letter many computer keyboards have to the Greek mu symbol.
Do not blind other drivers with your high beam headlights. Dim your lights by switching to low beams before you are 500 feet from a vehicle coming toward you. If you are following another vehicle, change to low beams when you get closer than 300 feet. Use your high beams whenever possible as long as it is not illegal (i.e., in open country when other cars are not near or on dark city streets when no other traffic would be affected by your high beams).
Pull the car straight back until the headlights are 25 feet from the wall. STEP 2: Make the following two measurements: Measurement A: From the ground to the geometric center of one of the headlight lenses. Measurement B: From one of the low beam headlights to the vehicle centerline. (Also measure from high beam center to vehicle centerline for 4 headlight systems) Note these measurements.
