There is a dimmer or brightness adjustment knob. It's on your dashboard about the 4 o'clock position on your tachometer. The knob has a tiny white pointer printed on the clear plastic next to it. You might want to check your owners manual for the dimmer location along with other controls.
That info is in your owner's manual The dashboard light dimmer is the same stem used to toggle between and zero the trip meters (and, incidentally, reset the "Maint" light after an oil change). Just turn the stem left (lower) or right (higher) to adjust the lighting to your preference. Cheers
The trip odometer switch on the odometer itself is the dimmer on Toyota Sienna. If you turn this switch all the way to the left your panel would become dark. Simply turn the switch to the right and all panel lights would come on. I had a similar problem and the manual bailed me out.
The dimmer switch is located on the turn signal lever. Pushing it forward will activate your high beams.and pulling back will return you to low beams.
You cannot use most fluorescent lights with a dimmer. Just about any incandescent bulb WILL work with a dimmer. Occasionally, when a halogen bulb burns out, it will destroy a dimmer switch but halogen bulbs are considered incandescent and other than that little problem they work well with a dimmer.
Inadequate ground connection!
Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem
Yes, they are known as dual-filament bulbs.
If you're referring to instrument lighting take a look at the stem you press to zero/toggle the trip meters. Turning that stem left will dim the instrument lighting, to the right brightens. That's the procedure for the Gen II (04 and later) Solara. The Gen I may be different. The information is in your owner's manual. Cheers
bad plug at the wiring connection
If your high beams still work it is the dimmer switch.
Not sure if this helps or not but on a 2005 Toyota Sienna LE, the dash-light dimmer switch is actually the trip odometer reset switch. Turning the trip odometer reset switch left or right controls the dash-light levels. Had it not been for the factory manual, and Google, I would have never known this.
The most common problem with LED bulbs is flickering. This can be resolved by ensuring the bulb is compatible with the dimmer switch being used, replacing the dimmer switch with one that is LED-compatible, or using a resistor to stabilize the electrical current.
