12V digital ignition timing light for accurate timing adjustments and diagnosing ignition system problems to help maintain your vehicle’s performance. Ergonomic and portable: lightweight, with an ergonomic design that enables one-handed operation for both professionals and DIY enthusiasts. Daylight-visible illumination: Xenon light beads provide high luminosity so timing markers are clearly visible in daylight and other lighting conditions. Safe and durable: red and black rubber handles offer a secure grip, and insulated wires protect against electric shock during use. 2-3 practical use scenarios: - Use when setting ignition timing on 12V gasoline engines to optimize performance and efficiency. - Use to diagnose timing-related symptoms such as misfires, pinging, or rough idle by observing timing marks. - Use in a professional shop or home garage for routine maintenance, engine tuning, and performance upgrades on cars and light trucks with 12V ignition systems.
