INNOVA 3551 Timing Light Review

INNOVA 3551 Timing Light is a great option if you want a basic gun for engine timing. It features a swivel head, which performs minor acrobatics that will help you get to areas that other timing lights could not reach. Furthermore, the tool could operate both in bright daylight and in the garage.

The one-hand operational timing light may have fewer features to offer, but it is priced reasonably if its capacity is concerned. The convenience of its use is paramount, particularly because it has an on and off switch that most timing lights do not have. Also, it has a patented skip circuitry test of up to 9,990 rpm.
