I put a piece of electrical tape around it to see if it helps but now it's more of a dull thud sound but just as loud. Might just have to try a new one. I can't find where I put my spares. I'm pretty sure it's original though because both the blinker and hazard relay are the exact same Wagner brand relay, which makes me wonder why they wouldn't sound the same or similar. I did notice the hazard relay was plain and the blinker relay had 2 yellow stripes around it.
