2001 V70-XC: IMMOBILIZER, SEE MANUAL.after changing parking light bulbs.

[lrock]

Wanted to put this on record in case someone might find it useful.

Had a bulb position light failure, went to change my rear parking lights (#4 position in the manual, 4th from top 2nd from bottom)
i used what was supposed to be the proper replacement LED bulb. When i went to start the car had an "IMMOBILIZER. SEE MANUAL" message. However, it still let me start and never cut fuel.
Assuming something in the electrical system was not happy with my replacement bulbs i took them out and put the old ones back in. Immobilizer message gone.
