I did double check by testing with a mate. First I put the lights on a shed wall and then tilted them down until I was happy with it not being up too high and then asked a mate to drive toward me on an open road. Seems like a lot of effort to go through but i myself hate when iam driving toward somebody and i cant see because of to lights being too high or bright. I am not one of those ignorant drivers my lights are only 55w instead of the overkill 75 to 100
