Investigated my front indicator not working and found its a combination of the below corrosion and a own bulb. The top brass nut that the lens screw, screws into was not attached to the back plate. So guess its allowed water ingress and its pooled at the bottom and rusted up. Squirted so acf50 in and let it penetrate for a bit before trying the old bulb, but that's a gonna. A new bulb worked. What part do I need to order for a 2004 roadster? Preferably one that won't take my eyes out 😂
