I just did a test of replacement LEDs in my 28Z. Since I have something 20 #1141 bulbs to replace, I figured I'd try just two first and see how they came out.
I bought a couple of these:
Amazon.com: Gold Stars 11568301 LED Replacement Bulb 1156 /1003 /1141 Base 120 LUMS 12V or 24V Natural White: Automotive
At $8 each, they are less expensive than most, but still on the pricey side.
They seem to have about the same intensity as the 1141 incandescent bulbs do. You can also buy replacements that are higher intensity (at a higher cost), but these seem to work fine.
Currently researching for even lower cost replacements before ordering the rest.
The current requirement is about 1/10th of the 1141 incandescent bulb.
