Well, when we search on google about how to adjust headlight beam, the posts on the search result will teach you to adjust the position of headlights by adjusting the headlight alignment screws. But, this method is just to adjust the light beam position (up, down, left, right), but can’t adjust the light beam if it is the scatted. Normally when we remove the original reflector and install an HID kit with the projector, we need to do this, or when we change a new halogen bulb which different to the original one, we need to re-position the height of the light beam.
If we are replacing the headlight bulb to be LEDs, we don’t adjust the alignment screws but adjust the light beam by rotating the socket on the headlight bulb. LED and halogen bulbs both work with the reflector. But, the different reflector has a different inner structure. LED can’t emit lighting with a 360-degree angle like the halogen bulb. So, when we make it fit into different headlight reflector, we gotta adjust it to have a perfect light beam. Watch this video, we will show you the detail.
