Hello everyone! I am fixing up my 1950 3100 Stock gauge cluster. I would like to put a blue led light for high beam into the speedometer gauge and two green led lights for turn signal indicators in the other cluster. My question is how big or bright should the led lights be? I have found so many different styles and sizes. I kinda like the small ones with a chrome ring on them so they look old school, they are listed as 8mm but they don't give lumen out put. How bright or what brand have you members used or tried? Please let me know and thank you for your help!
