What can be used to increase the LM3914N voltage

[Tessie Swift]

I want to use LM3914N to display the power level, 12v input, but it is not bright enough after being turned on. It is only 1.8v when measured with a voltmeter. What can be used to increase the voltage after turning on and the voltage can be above 3.3v? Many thanks for help!

If you download the lm3914.pdf file from TI you will see directions on how to program the current. I believe it is sinking current not supplying voltage. Also there are numerous web sites on how to build an LM3914 dot/bar display driver circuit. See:

For others; this is what it looks like:
