I swear, searching for these bulb numbers is the most horrible thing ever! It's like there are 10 million answers to one question. Very frustrating. I have found 7506 and 7507 numbers, 192 and 194. W5W and P21YW. The list goes on and on.

I just want to know the following:

TURN SIGNAL - ?
PARKING LIGHT - ?
SIDE MARKER (little dome dealy) - ?

PLEASE PLEASE PLEASE help me confirm these....THANK YOU!!!!

 

I put some Stealth Auto turn signal bulbs into my MCS recently. They were definitely 7507 bulbs.

 

So 7507 on the TURN SIGNAL BULB. Any others?!?!?!?

 

I picked up a set of the Sylvania SilverStars at O'Reilly last weekend, $10, P/N 7507A-ST

 

The parking lamps are "wedge" type bulbs, 194s.



The default color is plaiun white, but places like Autolumination sell amber ones (which I think look better and which I have installed in my car). They also sell silvered "stealth" bulbs in both white and amber, but honsetly you can barely see them.

Here's Autolumination's 194 BULB PAGE. Note that LED bulbs, while nice, might not fit in the very tight lamp housing. The halogen bulbs (which DO fit for sure) are near the bottom of the page.

 

So I have the following:

TURN SIGNAL - 7507
PARKING LIGHT - 194
SIDE MARKER (little dome dealy) - 194

It LOOKS as though the parking light and side marker are the same. Can anyone confirm that bit of info?

 

Its all in the back of your manual. Try there first

Do a search of the electrical forum, Someone posted all the light bulbs numbers

Finally, go here http://www.sylvania.com/ConsumerProd...lacementGuide/

 

Parking and side marker are indeed the same. Since you only need to replace the side marker bulbs if they burn out and can't see them behind the colored plastic, though, I'd just get spares at your local car parts place - they're only like $2 a pair. I'd not use colored bulbs in the side markers personally, if that's what you wee thinking, and silvered bulbs will give you no visible benefit...

 

VERY helpful....THANK you!

 

Different parts of the world use different bulb designations.
7507 and PY21W are equivalent
194 and W5W are equivalent

 

7507 = PY21W
7506 = P21W

Keep in mind, they are not directly interchangeable, as the PY21W has offset pins.

the front parking light is W5W. The equivalent to this is 168

194 is equivalent to W3W, which is slightly dimmer.

The side turn signal is WY3W, which is an amber 194 bulb.

The side markers (wheel well arches) are 194

194 & 168 uses the exact same base, so they are interchangeable

 

Once again, very helpful!

FYI, I have looked through my manual and I dont' see bulb numbres anywhere.
