But now, thank goodness, several of them have been restored and are open for tours. At the Umpqua River Lighthouse (above) you can take a tour up to the very top for only $3.00. It is the only Oregon coast lighthouse with a red flash in its sequence, so it has beautiful cranberry colored sections in its Fresnel lens. These Fresnel lenses were manufactured in Paris over 100 years ago and the guide claims that there is no way to get replacement parts anymore, so each lens is priceless.
The lens sections are actually prisms that focus the light into a beam that can be seen for miles. The entire lens assemble rotates around the bulb creating its distinctive sequence. These sequences are marked on nautical charts so mariners can distinguish each light along the coast. If you click on the link you can see the Umpqua Lighthouse just to right of center, near the tail of the North arrow. It says the light is alternating, two white, one red, every 15 seconds, 165' tall, visible 20 miles.
We didn't visit this one at Cape Arago because it's not open to the public, but we saw it from an overlook along Highway 101.
This is the Coquille River Lighthouse near Bandon. It is open for tours too.
At Cape Blanco Lighthouse the tour guide showed us these beautifully polished containers that were used to measure and carry the fuel up to the lamp via the cast iron stairs. These lighthouse keepers must have been exceptionally fit climbing those stairs several times a day.
