Signal, Brake & Interior Bulb FAQs
How do I choose the correct replacement LED bulb?
Check the original bulb number or the vehicle manufacturer’s bulb listing for the exact lamp position. Match the base, electrical contacts, voltage and available space. A matching vehicle model alone does not confirm every bulb on that vehicle.
Are 1156 and 1157 LED bulbs interchangeable?
Choose the size specified for your socket and lamp function. Single-function and dual-function applications have different requirements; do not substitute an 1156 for an 1157 unless the exact product explicitly lists compatibility. The same caution applies to 3156/3157 and 7440/7443 options.
What is a switchback turn signal bulb?
A switchback bulb changes between two colours for different functions. The Diode Dynamics 1157 HP24 listing uses cool white running light output and amber signaling, and specifies front turn signals with a clear reflector lens. Check the wiring and application requirements for the exact bulb.
Will LED turn signals need resistors or a flasher module?
Requirements vary by bulb and vehicle. Some listings offer resistor-free designs, while the Diode Dynamics HP24 switchback listing specifies a hyperblink fix using resistors or a flasher module. Read the product’s electrical compatibility notes before ordering; CANbus wording alone does not establish compatibility with every vehicle.
Which bulbs should I consider for interior lighting?
This collection includes compact 194 LED bulbs in different white colour temperatures. Confirm the original interior lamp’s bulb number and voltage before choosing one. For example, the Diode Dynamics 194 HP3 Cool White pair is specified for 9–16V DC; other products may have different ranges.
Can I use these LED bulbs for reverse lights?
Choose a listing intended for reverse light use and match the existing socket. The GTR Ultra Series 921/T15 bulbs are sold as a pair for compatible reverse light applications. Verify housing depth, socket fit and electrical compatibility before installation.
How do I choose the light colour and brightness?
Match the bulb’s colour and function to the lamp application and lens. Compare the exact product’s output and colour temperature rather than relying on LED count alone. Dual-colour decorative bulbs and switchback turn signal bulbs do not necessarily operate in the same way.
Are the bulbs sold individually or in pairs?
Package quantity varies. Some listings offer Single or Pair options, while others specify a pair or two-pack. Select the required package and check the included quantity before adding it to your cart.
