“Just like that.”
A Toyota owner says he was told a failed LED taillight would require replacing the entire assembly for more than $300. He took it apart instead—and says the problem came down to a single replaceable bulb.
TikTok user @desertwrenchers, a mobile mechanic based in Arizona, walked viewers through the repair on his own Toyota after he says he was told the LED bulb itself couldn’t be replaced.
Instead of replacing the entire unit, he removed the taillight to see what was inside. @desertwrenchers says there’s a trim piece next to each light that you can “pull straight out,” revealing “two 10-millimeter bolts.” He unscrewed both with a drill and pulled the taillight assembly away from the car.
Once it was disconnected, he pointed to a small circular piece held in place by a T20 security bit. @desertwrenchers says he eventually found the identical replacement part through Toyota, despite initially having trouble getting the part number, and shared that number with viewers.
He swapped in the new part, reconnected the assembly, and tested the light.
“Just like that we should have a working tail light,” he says.
The light came back on.
“Toyota wanted $300, plus,” @desertwrenchers said. “All it was was a bulb.”
He advised other owners who are told they need a complete tail light assembly to check the parts diagrams for their vehicle first, which may show the individual component and its part number.
As of this writing, @desertwrenchers’ video has more than 480,300 views.
On newer Toyota models, many exterior lights come as integrated LED assemblies rather than traditional, individually replaceable bulbs. In the 2025 Tacoma owner’s manual, for example, Toyota directs owners to a dealer if the taillights or stop lights burn out.
The same pattern appears on other recent Toyotas. The 2024 RAV4 Hybrid manual also lists the taillights and brake lights among components a Toyota dealer should replace, while its owner-serviceable rear lighting is limited to certain turn-signal and backup bulbs. A 2021 Highlander Hybrid manual likewise treats its tail and brake lights as LED assemblies rather than ordinary owner-replaceable bulbs.
That is different from older Toyota designs, where the company explicitly provided instructions for removing and replacing individual brake, tail, and turn-signal bulbs.
Toyota still sells individual replacement bulbs for some rear-lighting applications, including rear combination lamps, but fitment depends on the specific model and lighting setup.
In addition, Toyota’s parts catalog lists several genuine replacement rear combination-light bulbs and instructs owners to confirm that the part fits their vehicle.
That distinction is important for those wanting to follow in @desertwrenchers’ footsteps. While his repair may work for the specific Toyota and component he showed, it does not mean every Toyota LED taillight has a separately serviceable bulb.
Like any car manufacturer, Toyota’s own manuals vary by model and year, so owners should check the manual and parts diagram for their exact vehicle before attempting the same repair.
Many viewers focused on how much Toyota allegedly wanted to charge for what @desertwrenchers described as a replaceable bulb.
“And how much was that bulb?” one commenter asked.
“290 dollars,” another viewer quipped.
Others were more skeptical of the repair process.
“I’ll bet some dealers replace the bulb and charge for the entire assembly,” one commenter wrote.
Another viewer said they had run into a similar problem with a newer Toyota.
“Same problem with a 2023 Toyota Corolla; the dealer wants me to pay $1,200 for the headlight,” they wrote.
One person said they searched the part number @desertwrenchers shared and found a much cheaper option online.
“I just put 81536-42230 into Prime Amazon search and thru Amazon that part is $28.75. I learned this from a parts department when I needed a new LED taillight for my Chevy Silverado,” the commenter wrote. “Dealer wanted $799.00, was told to put OEM number into Amazon search and got full plug and play tail light for $98.99. Just make sure the one you order says OEM replacement because a lot of variations come up that have different circuit patterns.”
For one viewer, the video was enough to make them rethink buying another Toyota.
“Well then…. Guess I won’t be buying any newer Toyotas. Shame. I was wanting a RAV4 as my next car. Guess I’m going Subaru,” they wrote.
But another person argued the issue goes beyond Toyota.
“All new cars are like this,” the commenter wrote.
