We stumbled across a great value add on this one!
Most vehicles like this Toyota have switches, knobs and labels that are backlit by the headlight system. However, for some odd reason, too many of the automakers failed to get the message about transitioning into the 21st century and still used incandescent bulbs to light these up. LEDs (Light Emitting Diodes) are brighter and last longer than miniature incandescent bulbs.
Most manufacturers such as with this particular 2002 Toyota 4Runner consider these bulbs a non-service item. Basically, they are saying “when the knob doesn’t light up anymore, don’t buy a new bulb for pennies, buy the whole control at hundreds of dollars”. At Finn, we’ve found a happy middle ground. We searched out and spec’d replacement LEDs that plug and play in the same sockets as the original bulbs.
Let us take apart the component and retrofit the incandescents to LED! Its actually an upgrade. The new light is crisper, more reliable, consume less power per lumens, and wont heat up the neighboring circuits.
