Can TST TPMS Monitor Brightness Be Manually Adjusted
Updated 05/08/2026 | Published 10/05/2022
Question:
I recently bought the TST 507 Color. The unit will not stay bright enough nor predictably enough to read. Is there a setting I can change for the brightness or back light?

The brightness on the TST color displays, like what comes with the TST TPMS for RVs # TST-507-FT-6-C, have an auto-adjust setting for the monitor so there isn't a way to manually adjust this.
Since you're having issues with it not being bright enough you may need to change the location of the monitor. There is an "eye" sensor on the back of the monitor that can sense how bright the surroundings are so if the back of the monitor is in a cubby or shadow then you need to move it so it sees the brightness on your dash and it will, in turn, get brighter.

I have mine in the windshield with nothing blocking the sensor. It is so dim it isn't readable. Even if i move it in bright sunlight. Could it be defective?

I came here looking for the same backlight answer. The tire/axle icons are easy enough to see however the red hi pressure and low pressure text is extremely difficult to see even out of the sunlight. TST should really change the color
