Should your race car run a rain light? | Project vintage race Mustang

As we were planning on running some enduros with our 1965 Mustang vintage racer, this means the possibly of encountering wet weather. So we decided to install a rain light.

Lifeline USA offers an FIA-certified light for $199.99 that they claim is 3.5 times brighter than the competition. While installation is straight-forward, each sanctioning body may have its own rules requiring how it’s done.

Here is what the American Endurance Series requires:

Cars must be equipped with a combination of rain and brake light which must meet the following requirements:

  • 2.18.1. The rain light must comply with the FIA specification for rain lights.
  • 2.18.2. The rain light must be located on the rear of the car and must be no lower than eighteen inches from the pavement. It is recommended to place the light in the location that the license plate would normally be.
  • 2.18.3. The rain light must be the type that blinks at 4 hertz when activated and must become solidly lit when the brake lights are activated.
  • 2.18.4. At the discretion of AER and as conditions dictate, AER will put out a rain flag (a white flag with a red X) at the start/finish flagging station. At this time, and only at this time, shall the rain light be activated (including supplemental brake light functionality). For clarity, the rain light may act as a third brake light (but may NOT act as a rain light) when the rain flag is not present.

While the light is meant to be mounted vertically, we felt it better fit the Mustang when fitted in a horizontal position. We checked with Lifeline USA importer, James Clay, and he said that since top IMSA teams also mount them this way, he doesn’t see a problem with our installation.
