Hello, everybody!
My side( big) front roof marker doesn't work, so I would like to change the bulb. Any ideas what kind of Sylvania bulb should I use for this marker? I try to use Sylvania web- site, but I am not sure in those numbers I got from them. Whan is the Sylvania bulb code number should I use?
Thank You.

 

194 bulb

 

I've got the same number from Sylvania web-site, but owner manual of 2003 Hummer H2 said that it should be N168 for roof marker bulbs. I check another web-site Áutozone and found out that this number 168 from Hummer owner manual doesn't fit 2003 Hummer H2. It's a little bit confusing.
So I think that we are right.
It should be 194.
Thank you very much for your help.

 

By the way, from which source did you get this information from that it should be bulb N194?

 

168 and 194 cross. I have done a lot of h2. many bulb packages or boxes list both numbers.

 

This I true. Any wedge base bulb would fit which includes 168/194

 

Thank you, guys! It's very useful to know! Yesterday I changed burnt bulb with new 194 one. So right now I know what bulb to use in future!
