. These bulbs have a very high voltage that runs through them, even if the battery is disconnected. In some Lexuss, the highbeam is the same bulb as the headlight and it is possible for the highbeam to work, but the headlight be burnt out even if they are the same bulb and vise versa. Headlights grow dimmer by up to 20% over time and eventually burn out - for this reason, we recommend changing your headlights in pairs. Some Lexuss have high intensity discharge headlights, sometimes referred to as xenon lights. .
