leds in dash cluster? need opinions

ok wuts up everyone i need your advice on this project.

i want to replace the bulbs in the guage cluster for my 1985 pontiac trans am the bulbs it has are the cheap little ones with the color film what i was going to do is just replace them with red leds. is this good would it be too bright (annoying) can i just swap them out like that is there anything special i need to do besides adding the resistor.

do you think it will look right?? thanks in advance for your help.

the film is on the bulb itself

is there  a better way to make my guage cluster brigter besides adding leds or is this the best way?

I did this in my car, with UV or purple leds.  It looks cool, I liked it, I am changing it back.  Reasons, at night, can't see the unlit needle, its hard too look at being uv light and all, purple lights are not very bright.  If I was you, make sure that the leds are no taller than your stock lights, meaning that they don't get too close to the front of your guage cluster.  If you don't have iluminated needles, be careful. 

I myself are going to a new guage cluster.
