Headlights on 318

On my 318 the headlights seem so poor when compared to the ones on my 140h3. The cover is sparkling clear and the bulbs are new and seem bright for 156 bulbs but when outside in the dark they do not seem to put out that much light. I contacted The Light Guy out of Wi and told him about it and he said that 1156 halogen is brighter but he thinks the heat they produce will distort the plastic lens. Does anyone have any suggestions. Also He thinks if I spent the money for good LEDS THAT I would be dissappointed in the small increase in light for the exppense.
