Bulb Replacement Numbers

You're correct that normal bulbs and "Long Life" bulbs are compatible and they can be interchanged freely.
The big difference is in bulb life, a normal 3157 bulb has a rating of 1,000 hours on the high wattage filament, and 5,000 hours on the low wattage filament.
A Long Life 3157 has ratings of 2,000 hours on the high wattage filament and 10,000 hours on the low wattage filament.
I'm figuring that GM specified the LL bulbs in locations where they are critical like signal lights since you don't want them burning out prematurely.

Please Help, This is the Combat Zone :-) My light is out where the stick shift is (automatic) At nite when it's supposed to light up where the P R D 1 2 letters are it is dark- it went out the other day. Can you please tell me what bulb number goes in this
area. Also maybe you can tell me the best way to change it without breaking or shorting
out something. Thank You -- The Combat Zone

Search automatic shifter bulb and the first thread showed that there is a bulb somebody found one in his 2006 shifter.
It is a pain to find and change the bulb and there is no mention of the bulb number, mine burnt out 3 months ago it's on my to do list next spring

I just did a bit of research; the 2006 front turn signal (DRL) is listed as 3157 KX, and the 2011 front turn signal (not DRL) is listed as 3157 K. (Those are clear bulbs, some special edition cars use amber bulbs 5702 KA).
K means Long Life, X means High temp (can stand high temp, not is high temp).
There is a difference between 3157 and 3057, It is my belief that substituting is the reason some 2006 MY cars have melted DRL housings.
3057 12.8/14V 2.10/.48A 32/2CP (26.88/6.72W)
3157 12.8/ 14V 2.10/ .59A 32/3CP(P27/7W)
