How do i know if one out of the three bulbs go out

I find 530047721 is the correct purge bulb part number for the 358.795820.

Pictures I see show 2 ports not 3.

You may have the wrong purge bulb (?).

Certainly, you can use LED bulbs assuming you can find the right one for your machine. I found some on eBay for my Berninas and the light is great!!! So much brighter than the old yellow bulbs.

1. use old bulbs as samples by gently removing them with a soft cloth.2. Go to autopart shop or walmart,target or Canadian tire and you will find replacement bulbs. 3. Make sure you mark or place each old bulb into an envelope so you know where to put the new bulbs.

This model has three picture tubes and no bulbs or lamps.
you have provided a model number and if you tell me what set is doing or not doing I may be able to help.

Of the three wires going to the headlight bulb, one should be a ground.
If you unplug the connector you should have power on one wire for low and one for high, and one should be the ground.
If you have replaced one of the bulbs and know it is good, I would look at the dimmer switch, the headlight switch and the ground circuit.

If this is a DLP, which I believe it is, your bulb is blown. Look for an indicator light on the front of the tv. After you hear the bulb try to warm up two or three times the indicator light should come on and stay on steady.
I own a 57" Mitsubishi DLP and have replaced the bulb three times now. It was the latest and greatest technology when I bought it, but knowing what I know, I dont think I would buy another DLP.
By the way, get the bulb number then check ebay, by far the best prices.

Step 1
Remove your Contour's front grille. You can do this by raising the hood and removing two screws that are located on top of the grille.

Step 2 Remove the headlight assembly. The headlight assembly is held into the front of your Contour by three screws. Two screws will be located on top of the assembly, and one on the bottom.

Step 3 Replace the headlight assembly, if necessary. If you are only changing individual bulbs, make sure you replace the correct bulbs. Each assembly holds three light bulbs, including the bright, dim and turn signal bulbs.

Step4 Replace the headlight assembly and reattach the three screws to hold it in place.

Step5 Replace the front grille of your Contour and the two screws that hold it onto the front of the car.

• It is usually a good idea to replace bulbs together (in pairs). This will allow the bulbs to wear at the same rate.
• If you choose to replace only the individual light bulbs, do not touch the new light bulbs. The contact of your skin on the bulbs will cause the light bulbs to burn out much sooner.

Let me know if you have any further questions.
