Hi all, first post here.
My project, I have an old vehicle that I am slowly adding to. My current project is to add a gear position indicator. I am building a narrow panel with 7 individual cells with each having an LED's behind a covering mask. One LED for each gear position and the mask will be an acetate with the correct letter/number masked out for that specific Gear. The LED's will be switched via micro switches that will correspond to the selected gear. My plan has been to supply a common + lead with the required resistance for 14VDC (typical automotive working voltage). The ground side will be switched by the micro switches. Clear enough?
I went shopping yesterday and found what I believe are the perfect LED's.
LINROSE B4302H4-12V with integral resister
695 mcd (should be bright enough and maybe too bright depending on the heat output)
14Vf @ 10mA
I was expecting to need a resister(s) but this one seems to be set for an automotive voltage. Can some much more learned person tell me about these? Can I truly hook them up without any ballast resistor?
Thank you much!
Steve
