I purchased these lights and 11-09629 LED bulbs as what I expected to be, a modern, more reliable update over the usual GE-330 incandescent bulbs. I didnt have any previous experience with this bulb/fixture combination When I went to insert the bulbs, it appeared they didnt fit. I called A.S., explained my problem, saying the website showed the LEDs to be a replacement for GE-330s but didnt seem to be. The gal called product support and reported that she was told that only GE-330s would work in the MS25041 lights. Upset with what appeared to be a contradiction on the website, I took a GE-300 I had on hand to see if it would work. I had previously handled this operation gently, trying to avoid any possible damage to the bulb or fixture, but further experimentation revealed it is necessary to insert the bulb base with some pressure, into the fixture base, its like an interference fit, unexpected. I went back and tried the LEDs again and low and behold they fit the same way. So, happy ending. But I am disappointed that product support was not aware that the 11-09629 bulbs actually are replacements for the GE-330s, and that this bulb/fixture combination requires a little forceful fineness to install. Now I know, maybe this story will help others who want to do the same.

Unchanged in 50 years. Did the job for the Navy then, works good in the Bo now.

perfect

They are very well done and They work.

Used this as my ads-b ‘fail’ light. Worked out great

Fast shipping, easy order placement, thanks!

Good reliable light. Been used for more than 40 years. But for $65 (tax &shipping), you think they could have included a bulb and a decent wiring diagram. The drawing Spruce provides is a help but not much..

The press to test light came without a bulb in it’ How disappointing!

I was surprised to find that the dimming of the bulb is accomplished by a shutter, similar to what controls the amount of light coming through a camera lens and not electrically controlled. Not bad just different. Not installed yet. Just bench tested.

As expected... would have been nice if they would include wiring diagram..

Good quality, a bit over priced. Do not forget to order the bulb sold seperatly!

Ordered two dimmable press to test indicator, one doesn’t work properly, as the shutter for dim grip when I “undim” it unscrew the indicator head. It only happens on the one from oakgrisby the other one from dialight work fine.

Cant fit a 330 bulb in these indicators. Low quality manufacturing.
