Q: What part numbers should I be searching for in regards to the rear bulbs?

[Zim Hosein]

What part numbers should I be searching for in regards to the rear taillight bulbs? Brand a model number would be much appreciated since I tend to not trust certain websites with their compatibility info. Thanks in advance! :beer:

I find the Sylvania site pretty good. I have only come across one error.

Do you have an owners manual?

3157......

I do, but i was still a bit confused! :o

For example on Amazon.com I found bulbs by Sylvania, Wagner & Philips that are 3157K & 3157LL, I have zero clue as to the differences! :o

Thanks in advance! :beer:

3157LL The LL stands for long life. The K is standard

[RF Overlord]

It's the numbers that are important, not the letters.

K stands for Krypton-filled and LL stands for Long Life. They are the same thing, just different nomenclature used by different manufacturers.

Standard bulbs have no letter suffix. NA on the end means Natural Amber glass, while A means artificially amber-coloured (meaning a coating).

The owners manual is wrong....

Under hood lamp is a 912
Illuminated visor mirrors are 31mm festoon
Dual floorwell lamps are 168

If you ever need to replace a yellow bulb and you care about looks, get the NA they are a bit more expensive but cast a much nicer color.

The NA's are translucent the A's are yellow paint.

Now it makes sense! :o Thanks RF Overlord! :beer:

Good info, after reading your post I looked at the amber bulbs in the front and I can see some peeling, looks like a set of NA's are going into the shopping cart. Thanks jaywish! :beer:

[jaywish]

These cars originally came with NA's that may be what is there. Just a bit old

[EMAS]

Both NA and A bulbs are coatings and can flake off over time. The Amber is just more opaque than the Natural Amber.

You're most likely correct jaywish since none of the bulbs have ever been changed before, hence me starting this thread on the subject! :o
