Re: 12v Spotlights flicker
Conversion from halogen to LED lighting is not a simple plug-and-play process. The power supply is delivering more than 12v because the LEDs draw less current. The flicker could be evidence that the LEDs are gradually breaking down.

If this is the usual sort of halogen spotlight, it is usually supplied with a mains charger adaptor and a lead to charge it from the car cigar lighter socket.
Both those items are also commonly supplied with a range of car-related rechargeable items, torches, jumpstarters and so forth.
I have several such items and I find the 12 volt lead and mains charging adaptor completely interchangeable between all of them. Rechargeable halogen spotlights generally have a very disappointing battery life of around 20 minutes unless a very expensive professional model is bought.
If it is not a rechargeable type that must be permanently connected to the car cigar lighter, the power cord is usually permanently fixed to the lamp but if it isn't, the cable will need to be substantial enough to carry several amps - something similar to that of perhaps a large coolbox.
These Halogen bulbs are inefficient, and run so hot that they often damage the reflector and bulb socket if they are left on too long. Fortunately there is an easy fix for this. At most stores that sell the exact replacement Halogen bulbs (Lowes, Home Depot and others) you will see a selection of LED bulbs on the same display rack that will fit into the same socket the Halogen bulbs use. It is IMPORTANT that you know the code number stamped on the base of your Halogen bulb AND its voltage because some Halogen bulbs are 12 volts and some are 110 volts. If you can't read the labeling on the bulb, look for the wiring diagram usually glued inside the range hood or look in your owner's manual. Once you know your Halogen bulb's code number, look at the packages that the LED replacements come in. There will be a list of Halogen bulb code numbers that the LEDs are meant to replace. The male sockets on these LED replacements will be shaped just like the sockets on your original Halogen bulbs so they will plug in easily. However, just like LEDs bulbs that replace the old incandescent bulbs in your table lamps or ceiling sockets, they have an electronic section included in there base to run the LEDs and it makes the LED bulb slightly longer than the much simpler Halogen bulb. For my stove hood it meant that the bulb would not quite fit into the reflector in the hood. I had to use a Dremel tool to remove a bit of the reflector to get a proper fit. The LED bulb is just as bright but runs SO much cooler and uses so much less electricity that now I can use the range hood as a night light in the kitchen. I never felt safe doing that with the two Halogen bulbs since they ran so hot that they were burning the fixture that held them in the stainless steel hood and were melting the wiring entering the socket base. This upgrade to your range hood is well worth the effort.
Puzzled over this for a bit and finally pulled the dishwasher out from the cabinet. It's easy to replace the bulb from the outside. Socket is part of the wire guide which pops out with a screwdriver (see photo).
I can see threads on the inside dome but for the life of me I still can't get the dome to turn. Perhaps a special tool fitting the nubs would give one some leverage.
I replaced the 12v 5W halogen with a 12v 2.9W led assembly that has the same G4 base. Works well and should last longer than I will.
Hi Mary, go to batteryspec.com. In the search box put in TR2.6-12 even though it's 2.6, it equates to 2.8 for our spotlights. The battery is around $20 with a 1 year warranty, and has the same specs (dimensions, terminal position) as ours.
These spotlights are, essentially, automotive headlights powered by small batteries. Accordingly, take your old bulb to an auto parts store and match it to one of the headlight bulbs they carry. You'll find many bulbs that look just about right; the key is to find one (or more) that has the exact same base as your bulb so that it'll just plug right into place.
Before buying a new bulb, you can also double-check your old bulb with a simple test for continuity. Properly treated, these bulbs have a reasonably long life, and I wouldn't rule out corrosion in the bulb socket or some other issue that's keeping your bulb from lighting up. Of course, if you can see the torn or burned out bulb filament, it's pretty obvious that you're going to need a replacement.
The fuse has a lower AMP that is why it is blown every time you switch on the spotlights. In order for the fuse not to be blown, my suggestion is try the direct connection on the spotlights. Connect the spotlight directly to the battery. Just put a switch on it. If you want to use the spotlights, just press the switch.
