Thanks for reading this post.
My query is of a 1986 LTD CrownVic LX.
I have inherited this vehicle from my father & wish to maintain it as he would. It is near perfect.
The left cornering light is inoperative & I can’t find a replacement. Does anyone have information? Bulb suppliers & car parts shops are no help.
Also , should I use synthetic oil in my next oil change? 53000 miles! It is perfect!
Anything else to watch out for in this historic vehicle?

Thank you

Corner light is probably just a burnt out bulb. It should use a 1156 bulb.

Regarding oil, synthetic is fine. If it leaks any though, you may not want your money just dripping on the ground, but that's preference. 10W-30 is recommended as it goes.

Cornering light is an 1156, and it's the easiest bulb on the whole car. Socket is on top, twist it out, replace bulb, twist back in. Takes two minutes. I put LED's in mine for more light:

If a new bulb doesn't fix it, you could have a bad cornering lamp relay, and good luck finding one. Junkyard is your best bet (they're buried up under the dash). Same part for '79-91, all Panthers.

Use 5W-30 in winter, full synth for better flow at freezing temps. If you've got a leak, try adding a little brake fluid to the oil, it'll swell the seals maybe just enough.
