# Navigation Light Replacement The IF1200 has six LED navigation lights. One **Red** (Front, Port, left side arm), One **Green** (Front, Starboard, right-side arm), & Four **White** (two side arms, two rear arms).

Figure 1. Image showing how the light and the internal housing components connect.

If a navigation light fails to turn on it should be replaced. The lights are a twist-lock design and rotate into the housing receptacle to lock in place. (Figure 1) They are also secured with a rubber o-ring seal. (Figure 2)

Figure 2. Image showing the light inserted into the light housing. The housing is not removed. This is to show the 'twist-lock' assembly only.

Figure 3. Image showing an example of a basic, plastic "spudger" tool. This tool is used to help push the o-ring into the arm.

Installing the light will require a plastic spudger stick tool. This tool is used to push the o-ring past the drone's arm. (Figure 3) {% hint style="warning" %} BEFORE beginning, make sure the housing's receptacle and the light's notches are ALIGNED. {% endhint %} {% hint style="warning" %} REMEMBER: The light's internal housing assembly is NOT removed for this procedure. {% endhint %}

Image showing use the spudger tool to work around the arm to push the o-ring into the arm.

Once the light and o-ring are past the arm's opening, continue to make adjustments & apply light, inward pressure until the light is inserted deeper and properly twist-locks into the housing. If the light is not rotating and locking into place properly, you will need to begin again. Remember to make note of the alignments. The application of a small amount of dielectric grease or isopropyl alcohol, to encourage the o-ring into place, may be helpful. Nav Light Video {% file src="" %}
