    My usual truck ended up in the shop and had to take a 2000 KW bobtail (triple axle tanker) on a job yesterday. Well the job ended up running way behind which is typical. Anyhow, while I was looking around for the boss man to sigh off on my paper work, I noticed the head lights on my truck was flashing? This is a new one on me. I cut the lights off and on a couple times and that seemed to do the trick...so I thought. I got about 10-15miles down the road and the lights started flashing again! So I pulled over a fooled with the lights again until they stayed on. Once on, I started driving down the road and got another 10-15 miles when the head lights started flash again. It did this the entire way back to the yard!!

    Has anyone run across this before?

    There is a circuit breaker that keeps tripping, causing the flashing. You need to find the short or whatever is causing the breaker to trip, and it'll be fine.

    Yes, probably is circuit breaker tripping.

    May just be that breaker is old and tired.
    Has someone fitted high wattage light bulbs?
    Has someone fitted extra lights that also run through the breaker?

    You need to test the headlight current with an ammeter.

    Check the relay, most likely causing it. Like ptours93 swap it out for a less used relay like flood lights.

    The most common overlooked problems are related to grounds. You didn't say which hood you have, but i would check your ground.
