From 08.11. in Lidl headlight lamps are offered in set of 2 for 5,99 €: with 50% more luminosity or with blue light. I wanted to strike here in order to have replacement lamps at home. Now, however, the question arises for me whether, if a lamp breaks, I can simply replace it with a new one with 50% more luminosity and leave the other as it is? Or do or should both lamps be replaced in this case? my already used lamps have 50% more luminosity?
