With the amount you've spent modding Street, you could have actually upgraded to the ST170 by now![]()
Over a grand and a half would have allowed you to get the ST![]()
The ones i got are good quality, they don't seem any different than the Ford side indicators i got from Ford parts.
Do your bulb holders have the rubber washer on to make a watertight seal with the light casing? The only other thing i can think of why you getting condensation is if the little rubber hose at the back is blocked. I cant see the more expensive Ford part being any different really as they're both just plastic housings for the bulbs. £56 seems excessive for 2 pieces of plastic IMO.
