Features:

• Taillight controller can convert your front or rear turn signals standard flashing action to successive lighting.
• The 3-step sequential chase flash module boxes are universal fits for most cars.

Supports up to 21 W simultaneously?

• The “simultaneously” means the 3-step sequential flash module box can support up to (3) 21W bulbs at one time. This is because not all three light bulbs flash at the same time.

Retrofit Use?

• The pair of sequential flash module boxes are fit for many cars but retrofitting actions are required in order to install it. To install the 3-step dynamic flash module boxes, modifications such as wiring and wire extending are required.

How to connect the wire?

• All three light applications’ black wires must be tapped to the module box’s single black wire which is what we call the common ground/negative wire.

If the car uses the same light bulbs on rear turn signal and brake lights. Will I can use this box set for my turn signals alone?

• No, if your turn signals and brake lights share the same bulbs the dynamic flashing module boxes will not be able to make your turn signal lamps alone flash sequentially.
