First Claim
Patent Images
1. A timing light for use with an automobile engine having at least one cylinder, the automobile engine intermittently providing a firing voltage to the one cylinder, comprising, in combination:
- (a) flash means for providing a flash of light;
(b) couple means for interconnection to the automobile engine and for providing an input signal representative of the firing voltage(c) trigger means for activating said flash means in response to said input signal; and
(d) skip circuitry means, responsive to said input signal, for disabling said trigger means from responding to said input signal for a substantially fixed, predetermined period of time after every activation of said flash means by said trigger means, whereby said flash of light has a predetermined brightness.

Abstract
An automobile timing light for use with an internal combustion engine. The timing light includes a skip circuitry for regulating the time between flashes of a flash circuitry for permitting a sufficient charge to develop across a flash powering capacitor between successive flashes. The timing light thus provides a uniformly bright light flash irrespective of engine r.p.m.
