Hello. The LED strip that illuminated the nameplate in the truck burned out. It was a 12v tape because that's what it says on the strip (on the plus strip there is a description of 12v + in the place where the tape is cut). In this tape you can see that there are several diodes desoldered -...

You only have 3 choices 1. Joining 2 of the same pieces of tape in series 2. A suitable resistor 3. Lowering the voltage using a DC/DC converter or a linear stabilizer.

You connect the plus to the plus of one tape. You connect the minus of this tape with the plus of the other tape, You add the minus of this tape to the weight of the car. Unfortunately, these strips are 12V, so together they are 24V. During the operation of the car, you have 28.8V, which means that low-quality tapes will be damaged quickly.

This is what the burnt tape looks like. Can you please explain how to connect two sections in series? Added after 24 [minutes]: Well, I have a charge of about 28.2 - 28.4. This tape shone for me about a year and probably burned not from the voltage but from the water that got into it, but I can't say for 100%.

I connected it as shown in the picture only to the 12V power supply, unfortunately it does not work, and it should, right?

Power polarity correct? It should glow, just dimly.

Well, it shouldn't, because if you connected the 24v power supply in series then

Yes, correct polarity. the cable that protrudes I will give a plus and on the other tape I will give a minus

Hello. After all, you gave 24V voltage and that's how the 12V tape is connected to the 24V voltage.

OK, I need to get a 24V power supply and check. I thought 12V would pull it, but it will glow dimly. No resistor or regulator will be needed, because as the founder of the topic, I want to put these leds in the truck.

I powered the LED strip connected in the above way for lighting the garage door, but unfortunately the time switch does not work. The tape is always on. Anyone have any idea? I described a bit more here:

Hello. The LED strip that illuminated the nameplate in the truck burned out. It was a 12v tape because that's what it says on the strip (on the "plus" strip there is a description of 12v + in the place where the tape is cut). In this tape you can see that there are several diodes desoldered - maybe it made the 12v tape work under 24v? I am asking because I have a 12v tape and I would like to use it. I know there was already such a topic and it was written about serial connection. However, I would like someone to tell me in simple language if it is possible and what is the easiest way (without soldering additional components or resistors.

Topic summary

The discussion revolves around converting a 12V LED strip for use in a truck's nameplate illumination, specifically addressing the challenge of operating it at 24V without additional soldering. Users suggest three main options: connecting two strips in series, using a suitable resistor, or employing a DC/DC converter. The importance of correct polarity is emphasized, as incorrect connections can lead to malfunction. One user shares their experience with a burnt strip, speculating that water damage may have contributed to its failure rather than voltage issues. The conversation also touches on the need for a 24V power supply to ensure proper operation of the LED strip.
