getting ready to do my climate control Options

[Zimluura]

i'm getting ready to do my climate control in blue leds.

i'm thinking that for *each* of the 3 special toyota bulbs in the unit i can maybe put in 3 leds in a series cluster with a resistor (so 9x 5mm leds providing backlighting and 9x 3mm leds for each active button indicator). does anyone know what voltage those special bulbs normally get. i'm sorta assuming 12v is safe (though my voltmet4er says my cig lighter is 14v).

at 12v my resistor calculations...

...are telling me a 68ohm resistor for each cluster is the way to go.

i've got a little bit of experience with electronics. but mostly just replacing leds that are already in there. does this raise any red flags for anyone? does it sound like a good idea (to improve light dispersion)?

also i don't know much about power ratings, but i'm assuming that everything is fine if the power rating of the resistor is greater that what the led calculator says the circuit requires. can anyone tell me if this is an accurate assumption?

thanks in advance

i was thinking of replacing each bulb with a series of 3x 5mm leds (bent outwards to help light dispersion) and a resistor.

as for indicator lights i was going to just go with a 3mm blue for each (so 9 more leds, but in 3mm instead of 5mm).

DmVinny most of my pre-planning has come directly from your site, so your take on this idea means allot. think it sounds like a good plan? think i'll have the space in there to do the led clusters? or maybe should i spread each one out with wire so the leds are really spread across the unit?

don't worry, i wouldn't think of holding you responsible if your advice lead me astray.
