I installed sidemarkers on my 99 sedan over Christmas break and initially, the sidemarkers alternated with the front and rear signal indicators. Now a few days ago, I go for a "spirited drive". I stop at a stop light to turn right, and look to my right at a building with a large glass mirror and my signals and sidemarkers are not alternating anymore but rather they are all in unison. They went on like this for maybe 3 or 4 days, and now they're back to alternating. Does anyone have an explaination for this? It really doesnt matter to me what they do, I (nor anyone else I know) knows how to explain this. Any ideas?
