1989 325i intrument panel question

I own a 1989 325i, on the instument panel, lower center, there's a small row of about 6 lights. The first few are green, then a yellow and a red. They are all lined up on the bittom. The yellow one has been on for a while and I was wondering if anyone knows what they mean. The red one also went on, but flipped off shortly after. Thanks!

Took this out of my E36 manual:

Green - As the number of illuminated green lights becomes less, this an indication that the next service is due shortly.

Yellow - If the yellow light and one of the inscriptions OILSERVICE or INSPECTION comes on, the appropriate service is due.

Red - When the red light comes on, the service interval has been exceeded.

thanks. Do you know if there is there any way to reset it? I just did an oil change so I'm sure that's why it came on.

here ya go . .
