Default another question on bulbs

It does, but it's a 1156R LED. They're made to replace the filament

bulbs,
so guess it has an internal resistor. Maybe that's what the R stands for.

OK, after a few minutes of "Googling" it appears that the "R" (as in
other lamp types) stands for RED. The LED (also called 1156R) fits the same
socket, and glows red, but with less current draw. The same vendor sells a
"resistor pack" to use with the LED version to increase current draw to
match a standard "filament" type 1156R.
Now, this is my guess, that IF an LED type 1156R is used with the
"resistor pack" (in parallel with the lamp, I presume), then the resistor
pack should be removed if a standard filament lamp is the replacement.
Apparently some circuits (such as automobile turn signals) use the lamp
overall current draw to control the flashing frequency.

Does any of that make sense?
