Dash lights

Theres nothing wrong with the charging system. When I turn the knob to brighten/dim the dash lights its kind of iffy, . . . goes brighter then cuts out, brighter . if you find the "happy place" it stays fine. Driving v.s idle has no difference. They dont dim and extra with the headlights on or even the highbeams.
I think its just a matter of cleaning the contacts, I'm sure the light knob has some corosion on it and the blub sockets too. After finding some other posts about LED dash lights I think I will order some. I'm going to sick with stock bulbs for everything other than the gauge back lights; those get LED.
One question, as I looked on the site for the LEDs (superbrightLED.com) I think, i see someone talked about polarized light problems here. What EXACT bulb are you guys using in your dash? There are the "normal" LED bulbs with 6 or so LEDs that have 12 or so lumens and then the other "funky" polarized more expensive ones that kick out 60+ lumens. Which would you reccomend?

Anyone upgrade their headlights? Thinking about something a little more bright there too. I drive in detroit so being seen is a big deal lol, crazy city drivers :(

On another note, thinking about disk brakes upfront. Is it really worth going with Power disks or would manual disks give me enough of an upgrade over my manual drums. I have small bolt ralleys on it now with drums X 4.
I might buy a "junkyard" conversion kit my buddy has from a 74 dart with disks up front or are there any good aftermarket small bolt disk kits?
