Is it dangerous to drive with a faulty ballast?

Yes, an unreliable or dim headlight significantly reduces your visibility and how well other drivers can see you at night — repair promptly.

Should the bulb be replaced along with the ballast?

It’s worth checking the bulb’s condition at the same time, since bulb and ballast faults can produce similar symptoms and are sometimes related.

What is the ballast made of?

An electronic circuit board that steps up voltage, housed in a sealed metal or plastic casing.

A failing ballast can struggle to maintain a stable arc within the bulb, causing visible flickering or colour shifts before it stabilises, if it stabilises at all.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
