Driving regulations not commonly known

About 9 years ago I was pulled over for a broken tail light and for not following the curvature of a turn lane. It was mostly for the tail light which only had the red outside cover broken just enough to have the light inside glow white instead of red. Pulled over at dusk when my lights were on, in Burlington WA on Highway 9. I told the officer I was rear ended and was working on getting it fixed but was short on money and time to look for another cover for my 1976 Dodge Aspen. Not exactly the kind of car to have replacement parts readily available. Luckily for me, I got off with a warning and was forced to look for parts sooner than I had wanted to. I did find the red tail light cover I needed at a local wrecking yard but still was annoyed at having to replace it because the car drove fine and I did not have the money for repairs. I had no idea I could get a ticket for something like that.

Today I looked up on the internet to see if there was such a regulation about vehicles with broken tail lights. There is an addendum that states that the tail light must shine red instead of white. That is how I was pulled over. Even though the red cover was broken it was only broken about 2 inches but it still shone the light as white and not as red like it is supposed to be. Now that I know the tail lights should be red, I know that if there was another accident, I should have to get it fixed right away to avoid a ticket.
