Ive just bought an 03 Euro Lux a day ago, but not from a honda dealership. After the rains in Perth the past couple of days ive noticed the driver's side headlight has this same problem

I doubt that the euro will still be under warranty as its an 03. Am I able to take it back to any Honda dealership even though its not under warranty anymore? or should I take it back to the dealership that I bought it from?
