Hello Kris from Calgary and thank you for the inquiry on the Lightforce Lens Cover.
This part is sold individually. Order two if you would like two!
Here is the link to get back to the ordering page:
can these be used with 170s for fog lights on normal roads? can 170 without filters be used for foglights on normal roads?
Answer this question
This filter just changes the light color not the beam pattern. Lights will say spot, long range, driving or fog, this would be the beam pattern. You would want to purchase a fog pattern light and then if they make a yellow cover you could use that to change the light color.
