Why won’t my LED tail lights work?

Or, do your tail lights not work correctly? The reason for this is your cars computer thinks your bulb in burnt out. LEDs don’t use much power and don’t put a the current draw (LOW resistance) needed across the terminals of your tail, signal, or break light.

Why are my brake lights working but not my tail lights?

Dislocated or Damaged Wiring

Damaged or disrupted wiring can cause tail lights not to work, but brake lights are. The two lightings use different wiring as each bulb has got its power supply. A recent accident at the tail end of your car can increase the likelihood of this problem.

Do LED tail lights need a load resistor?

LED lights are excellent when powered directly from the battery or in addition to an existing circuit; however, this is not the case when used to replace OEM tail-lights. … Load resistors are needed on indicator lights and, depending on the base vehicle, perhaps on tail, stop and reversing lights as well.

Do LED tail lights burn out?

LED tail lights have a high failure rate. Fortunately, they’re easy to repair or replace as a do-it-yourself job. … This will lead to LED burn out or dimming of the bulb. In the event of a dimmed or LED burn out in your tail light, take your car to the dealer to have it inspected and replaced if necessary.

Is there a fuse for tail lights?

Once the fuse that controls your tail lights is identified, it can be tested using a fuse tester, which will light up if the fuse is good. If it doesn’t light up, the fuse should be replaced with one of the same size and amperage. On certain fuses, you can visually see a break in the metal wire inside a bad fuse.

How do I fix my tail lights?

Is the brake light and tail light the same bulb?

In many vehicles, the brake lights and the tail lights are located on the same globe. In other words, the same external covering is over both lights. Your vehicle’s might be a bit unique, with separate globes. … On most vehicles, the tail lights are red and the brake lights are a more luminous red.

What happens if you don’t use a resistor with an LED?

When hooking up an LED, you are always supposed to use a current-limiting resistor to protect the LED from the full voltage. If you hook the LED up directly to the 5 volts without a resistor, the LED will be over-driven, it will be very bright for a while, and then it will burn out.

Do I need a resistor for LED?

LEDs typically require 10 to 20mA, the datasheet for the LED will detail this along with the forward voltage drop. For example an ultra bright blue LED with a 9V battery has a forward voltage of 3.2V and typical current of 20mA. So the resistor needs to be 290 ohms or as close as is available.

Are LED tail lights worth it?

LED tail lights may last for 10 years or more because they are highly durable. Unlike their traditional incandescent counterparts, they are less susceptible to breakage because they do not have a filament and the heat they produce is highly concentrated.

What is an error free LED?

CAN-bus Error Free LED bulbs are LED bulbs that have resistors that are internally/externally attached. … The resistor’s job is to mimic the power draw of the stock incandescent bulbs to trick the computer to think that the bulbs are drawing the same rate of power so the vehicle does not throw any error messages.

Can LED lights be repaired?

A LED light bulb is a modern and efficient light source. … Traditional incandescent light bulbs cannot be repaired at all, while in LED bulbs you can repair almost everything. You just need to find the malfunction, make some repair and prolong your light bulb lifetime.

Does AutoZone fix tail lights?

How much does it cost to fix tail light wiring?

Replacing one brake or tail light bulb in an average car will cost $10-$55 labor plus the cost of the bulb ($1-$7).

What is a tail light relay?

Checking Fuses. Step 11 – A tail light control relay is used to help shoulder the electrical draw many bulbs can cause on a single circuit, this task is carried out by the BCM (body control module). The headlight/running light switch is used as the trigger circuit which sends a signal to activate the relay.
