I know some people have tried it. I was just wondering how many bulbs I will need for it? Also I think the bulb size is 194, if this is wrong please correct me? Thanks for your help.

 

pretty sure there are 4 194 bulbs back there

 

ok thanks for the help.

 

Are they hard to change? I know how to get to the gauges but then Are there just screws that hold the bulbs in?

 

you'll see 4 little brown "twist caps" on the back of the gauges...just turn and pull it out and the bulb is in it. its really easy!

 

ok thanks for the help

 

aren't they 168? I'm always confused by this. I was thinking of getting some 194Superwhite PIAA LED's, but I'm not sure if the LED's are bigger than a regular 194 bulbs?

 

I never really figured the difference between 168 and 194...I doubt there are any major differences to complicate this install! most sites list them with a "/" in between (ie- 194/168 bulbs). I know for sure I put 194s in my gauge lights last year though.

 

Has anyone put blue ones back there? Did it look good? Got any pics of it done?

 

From what I could tell, there is no difference between 168 and 194 bulbs. They are all cross referenced as interchangable on the websites selling bulbs that I came across.

However, I do not recommend LEDs in the instrument cluster. I tried the exact LED you are talking about (PIAA), and while the color was terrific, the light dispersion was poor. I think it has to do with the inherint directional light that the LEDs put out, while a filament bulb will spread out in all directions better. I have some polarg bulbs on order, and I expect them to be much better. They are pictured here in a 240sx cluster:

yes there 194 bulbs back there. but the problem is that the back of the guages has a green covering over the back of it if you have a gxe. the only way to get it off is to sand it off. i dont know if the led will work right but the blue lights will eventually fade. it was a good idea i thought at first also but it ended up just being a pain just buy the reverse indilow guages from south west auto works for 55 dollars you will be much happier. trust me. just my 2 cents

 

ngthing did it.
