Hella is just one of the many good brands.

Stock Preve halogen = bad spread compared to HID and LED.
HID in stock (halogen) projector = please don't do this. The beam scatters all over the place. Performance is worse than stock halogen.
HID (retrofitted) = much superior lighting, clean cut off and the beam goes damn far, on a dark knight the beam is visible around 200m away. Downside, on rainy night, visibility is almost no difference than stock halogen. This leans towards the color temperature. Advisable to get 4300K.
LED in stock (halogen) projector = just a bit better than halogen bulb.
LED (retrofitted) = brighter than retrofitted HID, but the beam does not go as far as HID.

Preve headlights are cold-sealed (permanent) from the manufacturer (not Proton), so they can't and won't change just the lens. If your car is still under warranty, get them to change the entire headlight assembly.

One side of headlight is around 700+ IIANM.

Refer to the image below, if the glass is not clear, light cannot be projected at optimum level.

Late but as promised.

Nice cut off that won't glare incoming or vehicles in front of me.


If you look carefully, the lens is a bit deeper than the stock halogen projector. You can see the gap between the lens and shroud, and compare it to the stock projector lens.

He's a car dealer himself lol

Always pump when your tyre is cold. I always go to a petrol station near my home around 300m at 7am.

Need to discern actual foggy or looks foggy.

Most of the times the reflection may make the lens look foggy.

For actual foggy, it looks frosted like a blind man's cornea.

Just noticed some noises on the way to work today, more prevalent at right side. Suspect either alternator or timing belt

I'm gonna change my current 215/45/17 to 215/50/17, test drove a Suprima with that setup and it's not as bad as I thought when driving on potholes.

It's just a minor mistake on their part, your warranty isn't going to be affected since all the itemized billings are in their system anyway.

Changed mine outside with NGK Laser Iridium around 300-350, can't remember. It's the same stock model used by Proton.

Dashboard rattling is a common sign of really worn out engine mounting.

For how much were you charged for replacing timing belt? Did you change the auxiliary belt too?

'Optimum' speed to drive around in this car is 80kmh (2k rpm) to 120kmh (2.5k rpm).

Headlamp or the bulb? Bulb costs RM20-RM30, brand new headlamp unit costs 700+

Rough estimation of installation service charge in Klang Valley?

Going to change the timing belt, auxiliary belt and water pump outside since my warranty is going to expire in 3 months.

Depending on shops, yes. But note that I gave a range, 30 sounds right.

Might as well retrofit with xenon or LED projectors

If you didn't play with camber setting before, it's unlikely to go wrong. It's usually the alignment.

Must be lemon unit. I don't have problem of misalignment.
