Be very careful with the Superstar bulbs. I used them for about a year. One night my dim lights on the passenger side went out. I tried to change out the bulb and couldn't. The bulb plug had fused to the housing - melted right to it. I immediately took the other one out - almost would not come out. Went to the auto parts place and got replacement bulbs and sockets and changed them out. I have since heard of nightmares of wires burning and causing fires, etc. Be sure the bulb is the correct wattage for your vehicle. My old 190E could take the Superstars but my current 420SEL could not.
