As with other lighting systems, the HID lamp system or whiter headlamps bulbs will not cause unwanted glare or discomfort to other road users if they are properly aligned.

For many new vehicle makes and models with factory-fitted HID headlamp systems, vehicle manufacturers have incorporated an auto-levelling feature, which automatically adjusts the headlamp angle and direction based on road and driving conditions to minimise glare. Some vehicle manufacturers are also attempting to reduce glare by changing the constitution of the glass used in the vehicle's headlamp, windscreens, and windows.
