LED Beacon- Red or White


Raptor05121

Recommended Posts

I have two strobes- factory location on the belly (which is INOP) and then another which was 337'd on the top of the empennage back in the 80s. That one still works but the strobe tube is dim and flashing fast, so it's on its way out.

So I plan on doing the Aveo RedBaron in both locations with them synced together. However, I cannot decide if I want Red/Red, White/White or combination thereof. Per Aveo, the white is brighter (Class 1) where the red isn't as bright (Class 2/3), BUT, I fly at night often and the top strobe illuminates the entire tops of the wings at night, and the white strobe does get annoying to a point where I do turn it off once I'm in cruise. So I'm conflicted.

It wouldn't be hard, but the top strobe is more noticeable than the bottom one. I don't know why Mooney put it down there. I *could* smooth it over, but I think it would be a waste. The A&P who did the 337 to install a strobe up there installed a doubler plate on the back that has about 150 rivets in it. Very ugly. So might as well use it.

That's a pricey replacement.  Have you considered:

You still have to make the red/white decision.  :(

I already have one of those (whelen version). One has a blown strobe tube and the other is on its way out. New strobe tubes are $150 each. Might as well upgrade to LED.

Red is definitely better for night.  While I prefer wingtip strobes for identification, especially daytime, the top and bottom in red are very good at big airports to both not blind other pilots and to have big airplanes notice you. The belly strobe or rotating beacon is good for reflection off the concrete to help 747 drivers see you among all the other airport lights.

Red on bottom/top, and white on wingtips/tip of tail.  The OR500 Whelen is a great nav/anti-collision combination that can be synced to your wingtip lights should you choose that direction...assuming you have, or would be installing an Orion wingtip solution of one flavor or another.

Alex, I would use whatever was least expensive for the belly strobe.  That is the one that keeps you legal but honestly doesn't help much if you're being overtaken by another airplane in the traffic pattern.

For the top I would use white, but I would put a piece of aluminum tape on the forward edge so that it would keep the light from illuminating the cockpit and wings.  You can probably experiment with some duct tape right now before you install the new one.  Again, the belly strobe keeps you night legal, the tail strobe you can do whatever you want.

During taxi, I would then keep the tail strobe off as a courtesy to others, and turn it on when you taxi onto the run way.

Alex, I recently removed my Whelen 90033 red anti-collision beacon on the belly in lieu of an LED model.  If interested, let me know.  I will include a new mounting gasket, bulb, and mounting ring + screw.  Brand new, they're around $500 easily, so let me know if interested.  If not, I'll include it on the "Parts for Sale" section.

You may want to review Whelen’s link below about approved anti-collision solutions...

Curious to see what feedback Boeing, Airbus, Bombardier, Cessna and other large aircraft manufacturers would have for you about their belly beacons being old and nostalgic...

It is not, but then you just become a Cirrus driver.

You need to refer to the Whelen chart. What you need for a 1960s Mooney is very different than what is needed in the 1970s models, etc.  Whatever you install new has to be at least as effective in area coverage as what the plane came with from the factory.

A belly rotating beacon or strobe is very good at nigh on large airports to have the A380 and B747 drivers see you as the light reflects off the pavement. Top mounted gets lost in the noise of all the other lights around.

Hey Steve, thanks for the offer but thats a completely different system. I have the circular Whelen self-contained unit. I think I'll eventually go with red/red

My pleasure.  For the price you were/are planning to pay for the Aveo, you may want to check out the below, it not already...dual mode red and white.

What LED did you choose?

I went with the Whelen model 90724.  Specifically, the 9072411 (lower, 5-hole mount, 28V) using qty. 5 100-degree countersunk screws.

http://www.whelen.com/aviation/product.php?head_id=12&prod_id=74

We enlarged the hole left by the 90033 by making a template, cutting carefully,  and dry-fitting the 90724 until we machined away just enough for a smooth fit.  We fabricated a support plate, given the new light is much larger by comparison, but the fit turned out to be very solid, and with the support backplate, is as solid a fit - if not more so - than its predecessor.  Overall, extremely happy with it.  I believe @Txbyker has the same light on his Ovation as well...will let him weigh in with his experiences, as the same mechanic did both our installs.

Yep, I copied Steve and it works great.  See attached video.
