    Increasing Gauge cluster brightness

    Has anyone done this? I can do it with my T2, but it won't let me keep it and set it at those levels. It is purely for a testing purpose.

    Reason I ask, is in the beater (the Suburban), I was getting tired of the dull low powered light, so I ordered a bunch from SuperBrightLEDs.com and it made a night and day difference. So much in fact, that once I got into the Caddy this week, I was rather let down by the level of brightness by comparison.

    Has anyone done this on our clusters? Ours being LED from the factory, are they hard soldered in-to-the board LED's? Or are they twist/pop out style like the 194's or 74's that I replaced on the 'Burb? I'd almost like it as bright, similar to when you don't have any lights turned on at night (I.E. the auto-dimming feature when you turn on the lights).

    Just so you can see, here is before and after pics of 'Burb;

    Before (regular 194 bulbs);


    After (warm white, 360*, 15 SMLED wedge base bulbs);

    I'd bet that they are soldered SMD LEDs ... I did a filament to LED swap in my monte carlo (as several had burned out) and had to desolder the little lamps and solder in some new LEDs and resistors.
    In the STS application I'd assume the T2 is allowing you to force full 'daytime' brightness regardless of it being day or night out as reported by the twilight sentinel on the dash and that is why it doesn't allow you to keep it set.

    The Monte used lamps like this in its cluster (with a couple of LEDs as well for the MIL and I think the airbags as well):

    Re: Increasing Gauge cluster brightness

    The T2 just allows for 10% increment changes to test the backlighting. At night, it usually drops it to 90%. So with the T2 hooked up, I can manually adjust up to 100%, but it won't let me set and save or override the auto-dim.

    I figure that they're hard soldered unfortunately.

    Negative. I need someone to help as the dash is a large piece and do not want to break it. If anyone's around Pittsburgh pa and wants to help in the undertaking it will be a learning experience and all meals are included hahahahhaha.

    I seem to recall someone discussing this years ago (back when I first joined), and it wasn't an easy process. As much as I love HUD (one of the things about all my Pontiac's that I miss), cost vs. benefit ratio isn't there for me to retrofit it. On top of which, It is not as if you're getting a full gage package in the HUD display. Just MPH, turn signals, radio frequency, and maybe in this particular application, a boost gauge etc...

    I actually like gauges, in particular the tachometer. "One eye tach, one eye track" is what I was always taught in drag racing 101. Granted that's more important for a manual transmission car. The point is, I like bright, legible, functioning gauges. Not a digital readout hovering in my lower eyesight. It's nice, but not the same.

    Re: Increasing Gauge cluster brightness

    HUD displays Speedo and Tach in sport mode and a check gauges message if you need to be alerted to the other gauges. It also shows radio channel, navigation direction with status bar, lamp indicators, and current gear in sport mode....

    I have all the parts needed for the retro fit, I have $250 bucks in it. Id say its well worth the cost if you do it right.

    Yeah it's nice being able to launch in manual mode and shift right before redline without having to look down at the rpms. It's right there where you should be looking when doing those speeds.
