it detects the voltage and behave just like the halogen,
At low voltage, it glows faint but very tasteful true amber color, such as DRL or parking light at night
At high voltage, it's super bright and yet again very rich amber, such as turn signal

and here comes the best part, when you have turn signal engaged, it'll cut the DRL/parking light function, so that you get a very crisp clean "on-off" transition. Halogens can't do that.

 

I have a '23 SR5 and refused to give up on having my LED bulbs, with my DRLs as well. I have not seen the path to actual success documented, so hopefully this will get someone pointed in the right direction. The only truly sustainable way to solve the SR5 DRL issue is to wire in a resistor (you can get away with a 10ohm resistor in the front (rear requires a 6 FYI), with a decent heatsink) in parallel with the bulb, through a time delay relay. I know many don't want to touch their factory wiring, but none of the bulbs (or kits) that I am aware of take the step of removing the resistor from the loop if the bulb continues on for a period of time. They all just continue to burn the resistor, for what could be hours on end. Plus, you can use ANY LED bulb you like, not just pricey ones or ones that look like they are wearing crowns, and they will last a lot longer as a bonus. I use $15 365 degree lit switchbacks, and they are fantastic...

 

I found Lasfit 7443 bulbs with built in resistors. These are the newest 2023 models the work perfectly like OEM bulbs. I have an amber pair in the DRL/turn signals, red pair in the brake light, and just a simple set of red LEDs in the parking light in the rear. I’m perfectly happy so far. As far as longevity, I’m not sure how long they will hold up but it’s the first pair I’ve tried that’s functioned exactly how I want them to. Can link or whatever if anyone is interested but on Amazon it’s just lasfit 7443 led they are about $50 a pair.

 

They will likely not last too long in your Tacoma, especially if you drive a lot during the day with your DRL's on. They will also create a lot of heat inside your headlight assemblies. It's not the bulbs fault though, it is the design choice that Toyota made when implementing the DRL's. I spent a lot of time on the road this fall and although I did not have any issues with melting of the housing I blew out 3 sets (two with the internal resistor like your Lasfit bulbs, and one with the external box type). In each case the resistor in one failed causing hyper flash in whichever direction, so I just replaced the set. The reality is that those resistors are not designed to be constantly on, they are meant for the service cycles of a turn signal, and in that capacity I am sure most last for years. Scrubbing off wattage creates heat, and heat needs to be dissipated, which is hard to do inside a closed space. Adding a time delay relay to a resistor circuit (any simple 10 second HID relay or whatever) when connected through the normally closed side, will use the resistor as usual until the bulb is on for "x" seconds (like when the DRLs are on) then the relay will open bypassing the resistor and stopping the creation of all that heat, if that makes sense. Obviously that requires wiring in your own resistors and relays, but honestly ever since I got my head around the fact that these resistors would be running at those temperatures for that long continuously, I knew I needed to figure out a way to get around that.
