This sign is clear by day, but the "EXIT ONLY" label is invisible at night.

There are two advance warning signs for the Avalon Drive Exit off of Highway 280 North just after the 280/380 merge. At night, the "EXIT ONLY" portion is barely visible on the second of the signs and not visible at all on the first. The reflectorization of the "EXIT ONLY" portions are eroded, and the light is out on one. This presents a danger to drivers since cars in the exit-only-lane may try to maneuver back into the mainstream of traffic at the last minute.
