LED Turn Signal Bulbs
Understanding Turn Signal Bulbs
Turn signal bulbs, also known as indicator lights or blinkers, are an integral part of a vehicle's lighting system. Their primary purpose is to signal the driver's intentions to make a turn or change lanes, alerting surrounding drivers and pedestrians. When a turn signal is activated, an electrical current flow through the bulb, causing it to illuminate.
How Turn Signal Bulbs Work?
Turn signal bulbs work based on the principle of an electrical circuit. When the driver activates the turn signal through the vehicle's controls, a signal is sent to the bulb in the form of an electric current. This current flows through the filament (in the case of incandescent bulbs) or the semiconductor material (in the case of LED bulbs), generating light. The flashing pattern is controlled by a relay, which causes the light to blink at a consistent rate.

Frequently Asked Questions (FAQ’s) on LED Turn Signal BulbsHow do you know which turn signal bulb is out?
You may notice that either your left, right, or both turn signals are suddenly blinking very rapidly. This is a sign that your turn signal bulb (or both bulbs) is failing and need to be replaced soon.Are all turn signal bulbs the same?
No, turn signal bulbs are not all the same. Each vehicle uses different part numbers, which will vary by manufactures. LED turn signal bulbs are the most popular choice when it comes to replacing the factory-standard incandescent bulbs for several reasons. LED bulbs project a brighter, longer-lasting, and more energy-efficient light than incandescent bulbs, which tend to become dull and dim.Do turn signal LED bulbs need a resistor?
Yes, one LED resistor is required for each turn signal bulb. Are you in need of a great resistor? You’re in luck! Underground Lighting can assist you in choosing the best product for your car or truck.Is it illegal to have blinking brake lights?
It is possible to receive a ticket for a rapid, continuously flashing red brake light. This is also a sign of a failing bulb. If you’re experiencing this issue on either one or both sides of your vehicle, it is in your best interest to replace the bulb(s) as soon as possible. Not only do you want to avoid receiving a ticket, but it is best to avoid any confusion on the road as well for safety’s sake.Why are my brake lights flickering?
If you’ve noticed (or been told by another driver) that your vehicle’s brake lights are flickering, this is a sign that the bulb(s) may be going out, or that there is faulty wiring in the circuit. Easy, “plug and play” installation makes this cost-effective, long-lasting update to your car or truck a no brainer.Why is my blinker going twice as fast?
Have you noticed your left, right, or even both blinker lights flashing twice as fast as normal? If so, this is a signal from your vehicle that your blinker bulb(s) are going out and need to be replaced as soon as possible. Not only is the rapidly blinking light and noise annoying, it is a warning to you to take action as a responsible driver before you either receive a ticket or the bulb goes out completely, resulting in a possible roadside accident.How much does it cost to replace a blinker bulb?
When it’s time to replace a failing or completely dead blinker bulb (or both!) cost can be an immediate concern. Longer-lasting, more energy-efficient turn signal bulbs that project the perfect amount of light output without casting a blinding glare on other drivers is well worth the investment. We have LED turn signal bulbs starting at $39.99. However, Underground Lighting offers LED turn signal bulbs that burn brighter and last longer than the competition.
