The landing lights on the A320 extend and retract when in use. Whilst not an aircraft limitation, common airline SOP is to retract them before exceeding 250 knots to avoid damage. You can hear and feel the vibrations from them in the cockpit at anything over about 200kts, to the degree that they include this in newer level d sims. Infact as they contribute extra drag, we often extend them early to get another extra bit of descent performance.
737 has landing lights built flush into the wing itself, so a speed limitation is not needed (Inboards)
