Scion iA headlights and brake lights turn off after a short period on Scion iA

Some Scion iA owners report experiencing issues with headlights and brake lights turning off after a short period, which could be attributed to several potential causes. One common issue is a faulty headlight switch that may overheat as it ages, leading to intermittent light failures. Additionally, some owners have encountered problems related to a malfunctioning brake light switch, which can prevent the rear brake lights from activating properly and cause unexpected light shutdowns. The interconnected nature of the brake lights with the taillights and dashboard lights means that any issues with the brake lights can impact the overall lighting system. Furthermore, unwanted electrical shorts, such as a shorted relay, can cause circuits to remain active when they should be off, resulting in erratic light behavior. To address these concerns, it is advisable for owners to inspect the headlight switch, check the functionality of the brake light switch, ensure proper operation of the brake lights, and look for any potential electrical shorts or relay issues.
