    Updated review. This has been working well for the past year. The interference is barely noticeable after cleaning the grounds on my rudder. Heres a video of the strobe function - I have quite a few aftermarket LED replacement bulbs in my plane now and its starting to trigger the auto squelch on my comms. These bulbs are nice but to make things easy, get the quality stuff or stick with incandescent bulbs.

    The one I have had some barely noticable intercom interference (ticking sound). Not enough to make me care about it. The bad part is that it only lasted a few flights. Currently trying the 4W version out. Will post a review for that one too after a few more flights. Props to Aircraft Spruce for making the return very smooth and easy.

    Worked great for about a year then just died. Not recommended.

    Agree with previous review. Lots of noise on VHF radio and cant use it on an airplane.

    Puts out large amount of wide band radio interference. Unusable.

    This bulb is approximately 2" in length.

    Q: Is your Aircraft LED Tailfin Nav replacement bulb meant to be mounted vertically or horizontal pointing to the rear? Part # 11-11372

    Per the supplier: It makes no difference which direction the bulb is mounted. The traditional method is for horizontal installation that replaces the current tailfin position light.
