95 RR classic SRS bulb

Does anyone have a lead on bulb replacements for the SRS on a RR classic. mine has a burnt out bulb and this causes a resistance code. it wont pass state annual inspection. the smallest I can find is an 85 wedge which is a bit large and too bright but it is the correct style/shape. not sure if the resistance would be too great
to satisfy the SRS ecu.
thanks

Pull one out of someplace else and see if it works. The puddle lamp for instance.
its much tinier than those on the hvac control of earlier classics, that would give a perspective of my situation. thanks for the suggestion tho.

they could work, thanks. another venue I have researched, the implant or install of a resistor in the line as a permanent load emulator.

to follow up on last post, I have read a few pages in reference to installing an online resistor. the existing SRS system is supposed to have one installed from factory, the Quandary. where is it supposed to be located? of all the pages I have read, not one mentions the possible location of the existing resistor. does anyone have a lead on the existence and or possible location of said factory load emulator resistor on the SRS system on a 95 classic?

to close this saga. I could not find a lead on the unicorn bulbs and by happenstance, I was visiting a junkyard looking for something unrelated to rovers, when I found a D1. disassembled the cluster and pulled the bulbs. removed the SRS harness, bisected said harness and found the location of the load emulator.
came home, located mine in general same spot, tested old resistor versus new, verified failure and replaced. had a friend clear the SRS code which read "The harness check resistor is measuring open circuit".
normally the SRS would blink with out a reason, it would clear and may stay off for a while or come back on immediately, or may blink upon start up and remain on. those actions would be emulated by old resistor when tested, the meter would read any where from .05 ohm to infinite when wiggled. the new resistor shows a steady 2.1 ohm which is it's stated value.

in case someone else is looking for location of said resistor, it is located on the SRS harness, just before the y split at the junction of the tunnel and firewall. same general area just below the heater pipes. there you will find the thin wire loom meets with a thicker wire loom. on my 95 classic it loops two brown with white stripe wires, the factory is crimped, I chose to solder versus crimping the new replacement.
