Did you upgrade the headlights? If you did by chance at some point, they may be draining more current out of the circuitry that it is capable of running, overloading it and causing these blips. Try going back to the factory recommended bulbs.

== == == == Bad headlight relay, loose connection, Bad ground. I cannot speak to your specific make and model, BUT most vehicles, some for many years, protect the HEADLIGHT circuit with "automatic resetting" CIRCUIT BREAKERS, instead of fuses. The purpose for this was so that if a short circuit occured while night driving, the headlights would only be out for a few seconds, returning momentarily to provide light for safely slowing and stopping the vehicle. This was a safety improvement over the old fuse system which once "blown" would leave a driver at highway speed, possibly in total darkness. Since the auto-resetting circuit breaker is a thermally operated device based on amount of current flowing through it, the cyclic rate of off/on will vary depending on the relative severity of the short circuit. Sometimes, if the short itself is only intermittent, the issue will arise only occasionally, and seem to "come and go." And of course, there could be other causes. Regardless of cause, the issue you describe IS a SERIOUS SAFETY problem, and you should take your vehicle to an auto electronics technician, or a qualified mechanic. He/she should troubleshoot your electrical system, identify the cause of the problem, and PROPERLY correct it.j3h.
