Flickering Headlight GS300H

[NishR]

Hi All, 

I need some quick advice pleaee 

I've noticed my driver's side Headlight flickering every so often. 

Its the original Toyota lamp/bulb. 

(Front Headlight Xenon bulbs Part No

Lexus D4S Xenon Bulb

Lexus Genuine Part Number: T90981-YZZCC) 

The original bulbs are about £70 each and I understand they should be replaced as pairs. 

Is the flickering definitely a symptom of a dying bulb or could it be something else?

Is there an argument to replace with original bulbs or could I replace with a cheaper alternative? (any recommendations would be most welcome) 

Many thanks in advance.

Yes the flickering is one of the symptoms of a dying bulb or possibly ballast, personally I change mine in pairs(as soon as one goes the other is not far behind lol).You definitely can get them cheaper or on the other hand pay a lot more depending on brand ,osram,Phillips etc

Nish,

I have one headlamp with low-cost bulb and one with high-cost bulb.

I cannot tell which is which.

Try swapping the bulbs over, side to side and see if the flickering moves with it. Would rule out a failing ballast?
