bulbs tail lights compact

[borjita]

Hello! I have disassembled the rear lights and I have seen that all the bulbs are the same (p21w or 1156) except the position light that is a smaller bulb, should I carry a p21w or is the bulb that is the original? If it is the original, what name does this bulb have?

Thank you!

I could believe that is the correct position light bulb. It needs to be significantly dimmer than the other 21W bulbs (brake, reverse, turn, rear fog) – somewhere between 4 and 10W. As there is just one of smaller bulb, it might be more toward 10W.

What exactly is written on the bulb?

in the bulb puts these numbers and letters: n918 12v r10w 37r E1 00211

being a r10w, the other numbers should be important for something?

I found the E1 helpful (EU approval from Germany), as it made me think of OSRAM, search for "osram r10w" and led to this web page with datasheets.

My Auto zone and the Osram site says a 325 use a 5W bulb 5007 and the ti uses a 10W 5008.
I think I prefer the brighter one due to all the rear end collision these days. I also seem to have the larger size bulbs.
