'92 500E Headlight&Foglight bulb upgrade

[01QX4]

hi,

I have recently changed/upgraded the bulbs (100/130 Lampa) in main headlights and also installed a relay so more amps go to the bulbs.

I like knowing if Lampa bulbs are any good because other aftermarket bulb brands are rare here!! also If changing the current headlight&spoiler foglight bulbs again to 100/130 Blue-Xe Lampa which claims to be 20% whiter&brighter. expert advice needed ASAP, thanks
