The definitive bulb size guide.

are the 194/W5W for the side markers or do the go under the corner reflectors on our headlights?

So how many of each bulb do we need for the gauge cluster for the P5? The dim ass bulbs in there now really irritate me. Hopefully if I put in some red 5-LED wide angle bulbs like I had in my Eclipse it will be brighter.

Anyone have a response to my previous post?

What about heat dissipation and the life of the bulb? On exterior lights, I have heard of the 194/W5W bulb socket being melted. Brighter light is good, melted socket is not. Also, for the instrumental cluster, I read that W5W is not recommended because of the shorter bulb life meaning you have to take the dash apart and replace it more often.

I replaced my bulbs there a couple of years ago. I think it takes two bulbs, but don't quote me. It is dim because of the orange condom on the bulbs and I replaced mine with amber 194, a little brighter, a little more orange matching the factory stereo. I was not a fan of the red cluster anyway.

You can take apart the cluster easy enough. If you need instruction, try to search for DaveB ring installation or ask anyone who has done that. It took a total of 10 min for me when I installed mine.

Getting the cluster out is easy. I had to pull it to install my alarm yesterday. Ok I guess I'll just order 3 - 4 Red 74's and 194's just in case. Thanks!

So, behind the cluster, there are multiple bulbs - of different sizes as well. I saw them when I was installing my rings. Now, without tearing it all apart again, does anyone know how many of each bulb there are back there?

Also, have we come to a clear answer onto what is the propper bulb for the rear turn signal?

Where do you search for low beam and high beam bulbs for your Mazda Protege?
