So I've been putting new lighting in my I30. While doing this, I thought to get the chrome coated amber turn signal bulbs. I ordered the first set, but contrary to what Silvania says (T20 connector), mine is a bayonet. I was advised to get 1156 bulbs. Those just arrived, and they do not fit either! Yhe bulbs I got have two small posts in line with each other on the connector, while the socket in my car has the two posts, but they are not in-line. Can I change the socket that my car has for these bulbs? Or can someone help me with what kind of bulb I really need to order. I don't want to keep spending money on bulbs I can't even use (spent $30 already). Thanks!

 

Rear turn signal bulb for a 2000 I30 is 7440.

 

I ordered those, and they are a different connector altogether. 7440 is a wedge, where mine is a bayonet (as is a 1156). Did Infiniti just screw up when making my car? lol

 

Looks like in another thread, someone said it is a 7507 bulb. Does this sound like it should be the solution?

 

Shouldn't the old bulb be labeled? :dunno:

 

The bulb number is PY21W. It is identical to the 1156 with the exception that the pins on the side of the bulb are at a different offset as the 1156. The 7507 is the same thing as the PY21W. I didn't like orange bulbs in my tails to i just stuck clear 1156 bulbs in it. You have to force them down a lil but they work nonetheless.

Edit: It seems the 1156 and 7507 run at different voltage and watts but I haven't have a problem with using 1156 to replace them on my I30t.

 

I already ordered the 7507 bulbs. I didn't see any possible way to get those 1156 bulbs in with how the pins are. These better work, or I'm just gonna leave the orange ones in. This makes >$50 I've spent on trying to replace these bulbs ($10 on a set of 7440s, $20 for two sets of 1156s, and now $24 for two sets of 7507s)
