# Navigation Light Replacement

The IF1200 has six LED navigation lights. One <mark style="color:red;">**Red**</mark> (Front, Port, left side arm), One <mark style="color:green;">**Green**</mark> (Front, Starboard, right-side arm), & Four **White** (two side arms, two rear arms).

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. <mark style="color:blue;">(Figure 1)</mark>&#x20;

They are also secured with a rubber o-ring seal. <mark style="color:blue;">(Figure 2)</mark>

This is to show the 'twist-lock' assembly only.</p></figcaption></figure> <figure><img src="/files/XCZs4pytpUnr315CojbI" alt=""><figcaption><p>Figure 3.

Installing the light will require a plastic spudger stick tool. This tool is used to push the o-ring past the drone's arm. <mark style="color:blue;">(Figure 3)</mark>

{% 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 %}

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.&#x20;

The application of a small amount of dielectric grease or isopropyl alcohol, to encourage the o-ring into place, may be helpful.
