Red 4x Light Bulb 1156 BA15S 21W Turn Signal Blinker Single Filament Lamp

I bought these for retrofitting antique car lights.

Changed to smoked lenses and the new bulbs worked great.

Good price

matched the other bulb perfect

These bulbs are the best I've found for use behind smoked lenses. They almost look black in the packaging.

What's to say about red bulbs? They work and are red. I might add if your buying these to install on the rear of a Yamaha motorcycle ,these will not work,the pins that stick out on the sides are not in the correct place to fit in the socket. It takes a different part number bulb.

Dull and too dark red barely visible poses a serious safety risk i switched out to a decent led bulb

The bulbs have a thin red coating on them, if the bulb is scratched at all, a white dot or white streak shows. When used in a white light fixture cover, the white streaks or dots show on the light fixture thus reducing the red light lighting. Bulb coating is fragile. I bought a red LED instead which is not subject to bulb scratches. The led works great, the bulbs are too fragile.
