Since my 12V / 5W bulbs are now gone, I need to install "in-line resistors" to cancel out the 2 malfunction messages.

that would mean (if my 2nd grade math is correct):
12 x 12 / 5 = 28.8
Still sounds a bit too high for side marker bulbs.
If I solder in inline resistors in the bulb sockets, what size resistors should I use ? What if the resistance is much lower than 28.8 (computed from the formula above), will placing larger resistors be the solution or do they need to be exact ? I don't want lesser resistors, correct ???

Thanks also to Mark Cummins for these directions, and brutal patience with my ignorance !!!

bi-xenons pic w/ simple question
Is the circled part the parking lights and do I have the correct replacement bulb for it?
Twin Pack 19168
Bulb Type 168 Wedge
Wattage 5w
Technology Super White BTW, is this one whiter than the Xtreme White???
Thanks for the help

that's the high beam light
there's the city light (the small one) that sits underneath that, and the corner lights also go on as 'parking' lights. which burnt out?

the light didn't burnout. I just wanted to replace the city light to a whiter one to match the big xenon projector. Is the above piaa part # the right one to replace the city light?

How do you remove parking light bulb?
I want to replace the parking light bulbs but I'm having difficulty removing them. Due to the surrounding area being very tight, I can't tell how the bulb is removed. Do you twist it out or just pull it straight out.
Please Help.

Your Recommendations for white City Light Replacements, Please
I replaced my city light bulbs (W5W) three years ago with Philips Blue Vision hyper whites, from England. I really liked the much brighter look (white, not blue, I would say twice is white as the OEM yellow bulbs).
Now, one bulb has failed and I assume the other is not far behind. Is there a newer W5W bulb, available in the US, that is at least as bright as the Philips Blue Vision? Need to know what brand, type and where to get them, please.

I replaced mine when they burned out with sylvannia silverstarz. Not sure if there as bright as the ones you used to have, but im content with them. I got them at pep boys.

I do not believe (at least through my observations at walmart) that SilverStars come in a W5W. They do make them in the H1, H7, H4, 9004 etc and are 55W. I have them on my C230 and like them. I have pictures if you would like. PIAA does make something similar in a W5W as Harris pointed out.
