How to perfectly aim your headlights for maximum down-the-road lighting

Lots of useful tips -

Using the average height of the side mirrors on a passenger car to find out how high to aim your headlights provides useful way to get maximum headlight beam height w/o ending up with your headlights aimed too high! While it's possible to end up with low-mounted headlights being aimed a little too high, as long as you're not getting flashed a lot by oncoming drivers, this method should provide a higher aim-point than the actual height of the Slingshot's headlights and produce more light down the road than headlights aimed at a lower point.

First is a video from Headlight Revolution pointing out that replacement LED headlight bulbs will probably need re-aiming -

The next video shows how different LED headlight bulbs may need to be adjusted for best bulb pattern orientation before adjusting the aim of your headlights -
