I haven't seen anyone with those chrome ones. I have the Silverstar turn signal bulbs, they look blue-ish when not lit, then glow amber. Here's how how they look when they're off...
The chrome bulbs would probably look cool too though...pretty much anything will look better than amber bulbs.
i tried a set from stealth auto that look chrome but turn amber, and before i could even install them the chrome coating or whatever started flaking off really bad and looked like crap. so if i had to do it over again, i would go with the silverstar ones, they look pretty sweet.
