I'm not surprised that the devil lights put out a pretty good light.

What you don't have with them is the internal diamond faceted cut to the lenses that make them reflect light back at an oncoming car - when your lights are off at night, parked etc. - as well as disperse the light a little better than a plain red glass lense as are the devil lights.

Do a little comparing between lenses.
Replace the burned out bulb, determine if both sides are about equal in brightness.
Then, replace one taillight lense with a standard 39 lense.

If Mr. Highboy is in the garage nose-in, wait till dusk, leave the garage lights off, turn on the parking lights and take note of any differences in taillight light intensity.

View the taillights from both left and right angles, 45 degrees or so.

Save the devil light lenses, they'll make good trading material somewhere down the line.

Now I'll shut up for a while....
