Innova Advance Timing Light 3555 — 0–60° Direct-Read Strobe with Skip-Circuit Test

Compact and precise, the Innova 3555 combines a direct-reading advance scale with a slim rotating barrel to make setting ignition timing faster and more accurate on conventional, electronic, and computer-controlled systems for both domestic and import vehicles. Its patented skip circuitry test and broad RPM coverage let mechanics and DIYers diagnose intermittent ignition problems while the clear 0–60° dial shows advance or retard instantly.

How does the Innova 3555 make timing adjustments easier?

The 3555 gives an immediate visual of ignition timing with a direct-reading advance scale and a narrow rotating barrel to aim at timing marks precisely. This simplifies alignment under the hood and reduces guesswork compared with indirect or estimated methods.

• Direct reading 0–60° advance scale for instant readings
• Slim rotating barrel for easier sighting of timing marks
• Bright strobe output for clear marks even in daylight

Can this timing light work on modern electronic ignitions and imports?

Yes—the Innova 3555 is built to operate with most ignition types, including conventional, electronic, and computer-controlled systems across domestic and imported vehicles. It connects easily and provides accurate strobe timing without vehicle-specific adapters in most cases.

• Compatible with a wide range of ignition systems
• Universal fit design for garage and shop use
• No special vehicle programming required for basic timing checks

What diagnostic benefits does the patented skip circuitry test provide?

The patented skip circuitry test detects intermittent misfiring or skipped sparks up to 9,990 RPM, revealing problems that steady lighting might miss. It’s especially helpful for troubleshooting rough idle or intermittent performance issues linked to ignition instability.

• Skip detection up to 9,990 RPM to catch transient faults
• Useful for isolating ignition coil, module, or wiring issues
• Complements timing checks with performance diagnostics

How do I get accurate readings and what accessories help?

Position the slim barrel so the strobe lines up with the engine timing mark and use the clamp and lead set provided for a secure, noise-free connection. Stable engine speed and a clear sightline to the mark yield the most reliable results.

• Use clamp leads to minimize electrical noise
• Run engine at consistent RPM while reading the dial
• Rotate barrel to optimize aim at timing marks on pulleys or sprockets

Who is this for: The Innova 3555 Advance Timing Light is intended for professional mechanics, automotive technicians, and serious DIYers who need accurate, repeatable timing verification and ignition diagnostics across a variety of vehicles. Its combination of a direct-read 0–60° scale, slim aiming barrel, and skip circuitry test makes it a practical tool for shops troubleshooting ignition timing, intermittent misfires, or performance tuning.
