Pop up lights. Delay?

Hi, I have a 1.8 1995 Mk1 & a 1992 1.6 Mk1
My question is why, when I use the headlight stalk the popups on the 1.6 raise, flash and lower immediately yet on the 1.8 there is about a 3 second wait before the popups lower. Is there a cure to resolve the 3 second delay. TIA

1.8 also fitted with the so called ( in bygone days) " Flash to Pass". It delays a couple of seconds as well in retraction, but I cannot claim it’s ever bothered me to be honest.

Yes, I guess it’s just one of those things. It didn’t bother too much but thought there may be a mod as my new 1.6 is so much quicker.
