Headlights Again

[EricW]

Hi List,

I flipped the lights up today to have a bit of a recce, prior to getting the
recommended replacement halogen lights from Repco and fitting them tomorrow.

I then noticed that the lights fitted to the car (94/1800 NA) are in fact
"Koito" brand Halogens.

The question therefore arises, Are these the OEM lights or have they been
changed from incandescent to halogen in the past and will I gain anything by
going to a different type of Halogen light?

I only got as far as noticing they were halogen and have not taken the
headlights apart, so I am not sure if the current lights are sealed or semi
sealed, the recommendation seems to be the Hella sealed unit.

Can anyone clarify this for me?

Regards

Eric
